This contains errors. The sentences are not correctly punctuated. But it is handy to review if one wishes to comment on what the presenter has claimed. 0:00 brain scans controlled studies evolutionary psychology and anthropology demonstrate that men and women are not 0:06 the same. we are physically and mentally different. we input process and deliver information differently. we evolved with 0:12 different priorities and we are marinated in different combinations of hormones. this leads to a misaligned 0:19 interpretation of reality which creates conflict not only in our love lives but 0:25 in our family lives and the lives of our children. the following is a list of 50 of these differences. perhaps if we're 0:32 aware of them we can interact with more empathy and better logic 0:40 men and women don't see in the same way from the very start of light hitting the retina to the information arriving in 0:47 the cerebral cortex the process is different in males and females for example the male retina is thicker it 0:53 has more M sells em cells are larger and are distributed across the retina M 0:58 cells are responsible for tracking the movement of objects the female retina is thinner it has more p cells p cells are 1:05 smaller and concentrated around the center of the retina p cells are responsible for identifying objects and 1:11 analyzing color and texture female babies like faces male babies like moving objects this isn't surprising as 1:17 we just learned males and females see different over a hundred infants were studied on the day of their birth they 1:24 were given the choice between looking at a moving mobile or a young woman's face the researchers were not told the sex of 1:31 the baby while they recorded the baby's eye movement the boys were twice as likely to gaze at the dangling mobile 1:37 while the girl babies were more likely to look at the face boys and girls like to draw different things most little 1:44 girls like drawing people plants and animals arranged symmetrically and facing the viewer they're more likely to 1:49 use lots of colors and the colors they do use tend to be warm boys mostly draw action scenes the dynamic move it's not 1:57 common for them to use more than six colors and when they do use colors they tend to be cool if you find yourself 2:03 thinking okay who cares kids draw different stuff keep in mind that most early grade school teachers tend to be 2:09 female with the feminine bias they tend to favor girls trying to be the correct type of art which can put boys off art 2:15 forever and it goes way beyond boys doing poorly in art class I always see headlines like boy suspended for drawing 2:21 a gun I think if teachers were aware of these hardwired differences they would stop raising concerns about boys 2:28 depicting violent scenes we should look back to the old proverb boys will be boys take a deep breath and relax 2:35 females hair better than males in the language and hearing centers of the brain females have eleven percent more 2:42 neurons than males females not only hear better but they can discern between a broader range of emotional tones in the 2:49 human voice this is probably because babies and it's a skill were born with a study 2:54 of infant on the day of their birth showed that girls will respond more to the cries of other babies than boys hey 3:01 soft-spoken female teachers before you label your little boys with attention-deficit try moving them to the 3:07 front of the class they probably can't hear you music affects us differently premature baby girls who received music 3:14 therapy had fewer complications grew faster and were able to be discharged faster than those who did not there was 3:20 no effect on premature boys males will automatically block out certain sounds a 3:25 study in the Netherlands monitored the brain activity of 17 to 25 year old males and females while they listened to 3:32 white noise and music the females had an intense response to both sounds the males responded to the music but 3:38 deactivated to the white noise as though they didn't even hear it this may be because during male fetal brain 3:45 development testosterone impacts the formation of the auditory system making a block out unwanted noise and 3:51 repetitious acoustic stimuli this is a huge issue in male-female relationships 3:56 a girl will say something to the guy and he won't hear her she will repeat herself several times which then makes 4:03 his brain interpret her voice as unwanted repetitious acoustic stimuli and before you know it it devolves to he 4:10 never listens or she's always nagging and a lot of us will get stuck in a feedback loop of unwanted behavior 4:17 creating this fascinating chicken or the egg scenario does my mom repeat herself 500 times because my dad can't hear her 4:24 or does my dad tune her out because she's repeating herself females can 4:29 verbally express their emotions better than males the key word here is can as 4:34 in have the ability to this is not a some may have you believe a difference 4:40 caused by societal gender norms this is a legitimate brain difference MRIs were 4:45 used to examine how motion is processed in the brains of boys and girls ages from 7 through to 17 they found that in 4:52 children negative emotions were localized in the primitive area of the brain the amygdala this part of the 4:58 brain has few direct connections to the language and reasoning are in the cerebral cortex which is why 5:03 it's difficult for most kids to verbally express how they feel then in adolescence a large portion of the brain 5:09 activity associated with negative emotions moves up from the amygdala to the cerebral cortex but this change only 5:16 happens in females a study from Germany duplicated this finding and went on to 5:21 conclude that both positive and negative emotions are processed differently in males and females post puberty judging 5:27 from this it's no wonder that men rarely want to talk about it men are wired to avoid contact with others when they're 5:33 going through a rough time and they even report thinking that women would want to do the same so before you get mad at 5:40 your boyfriend for his silence remember that it's literally difficult for him to verbalize his feelings boys naturally 5:46 use movements to think boys and girls of grade school age was studied to see how long it would take them to complete 5:52 conceptual math problems the boy solved the problems faster than the girls the researchers noted that when they asked 5:58 the boys to explain how they got the answer the boys didn't use any words they wiggled acted and gestured their 6:04 process words were a barrier so over the next following leash the researchers taught the girls to explain their 6:10 answers with movement they retested everybody and the girls were able to solve the problems as fast as the boys 6:16 it seems that boys and girls have access to the same circuitry but they use different circuitry as a default groups 6:22 of boys play differently than groups of girls boys larger playgroups focus on 6:27 the game itself rough-and-tumble very competitive confrontational establish dominance and test hierarchy claim 6:34 territory and monopolize toys show off their physical strength struggle for social rank and are more likely to use 6:41 threats girls focus and relationship-building take turns 20 times more often than boys do more 6:47 likely to make collaborative proposals and their pretend play is usually about caregiving and relationships these 6:53 differences also ring true for close relatives long tail macaws are six times more likely to engage in rough and 6:59 tumble play while the female macaws prefer babysitting the baby monkeys by the time boys are in first grade they'll 7:05 get a dopamine rush when they display their power and some studies have indicated that you animas Lee agreed-upon hierarchies are 7:12 established as early as nursery school and stay stable for at least six months and the boys at the top are not always 7:19 the biggest there the boys for at least likely to back down when it comes to conflict even males castrated at birth 7:26 and raised as female tend to be the dominant ones in the group the most interesting thing about group play is 7:32 that girls and boys will naturally segregate unless there's not enough kids could it be that kids prefer playing 7:39 with those who are similar to themselves boys and girls play with different toys at seaman Concordia studied almost a 7:46 hundred one and a half year olds and their preference for toys the girls had a preference for dolls and the boys had 7:52 a strong preference for trucks many would argue that this is a socialized to gender behavior but the thing about one 7:59 and a half year olds is that they have a lot of trouble correctly assigning others and themselves the correct gender 8:06 and naturally because the boys develop slightly slower than the girls they had more trouble signing other people and 8:12 themselves the correct gender if we assume that playing with sex specific toys is a social construct then it would 8:19 make sense for girls to have a stronger preference for girly toys because they have a better understanding of gender 8:24 but what they found was the opposite I'll repeat the results the girls had a preference for dolls but the boys had a 8:31 strong preference for trucks these results were duplicated and nine month olds which have an even poorer 8:37 understanding of gender even with direct intervention from teachers and parents 8:42 who encourage gender-neutral play girls will choose dolls over trucks as soon as 8:47 they're given the choice girls will play with their trucks as though they were babies and boys will play with their 8:53 dolls as though they were hammers or swords kids are so goddamn sexist actually all mammals are sexist male 9:00 monkeys preferred to play with toy cars and female monkeys prefer to play with dolls young male rats engage in way more 9:06 rough and tumble play than young female rats study any mammal they'll play differently depending on their sex 9:11 sexism as a hate fact boys are more likely to take risks researchers in Missouri studied the responses of kids 9:18 who wrote a stationary bicycle while watching a hyper-realistic stimulate when confronted with a hazard the boys 9:23 were much slower to break than the girls if it was real many of the boys would have been seriously injured the boys 9:29 also reported feeling excited during a simulated collision while the girls reported feeling fearful females are 9:35 easier to startle this was demonstrated in a scary stimuli study which measured fear through the electrical conductivity 9:41 of the skin women exhibits stronger emotional responses to the anticipation of pain males are more likely to 9:47 overestimate their ability when a professor looks at male and female students that graduated from the same 9:52 University with the same business degree he found that the starting salaries of the men were on average of four thousand 9:59 dollars more so sexist wait that's not the whole story it turned out that only seven percent of the females asked for a 10:05 higher starting salary versus fifty-seven percent of the males so the actual result of the study is if you're 10:12 confident enough to ask for a higher starting salary a regardless of your gender you're more likely to get a 10:18 higher starting salary but it's not all dandy for the boys overestimation of ability also leads to things like 10:24 drowning males are more likely to die from an accident than females as mentioned males are more likely to take 10:31 risks and overestimate their ability psychologists at Boston University estimate that this is probably why most 10:36 drowning victims are male boys are way more likely to do dangerous things they're way less likely to listen to the 10:41 warnings of their parents and they're way less likely to tell anyone if they do have an accident huge data shows that 10:47 boys are significantly more likely to die of an accident like the misuse of a firearm or a head injury from riding a 10:53 bike and this goes way deeper let's say that the same amount of men and women were to get head injuries the damage 10:59 would still be worse in men researchers at the Children's Hospital of Pittsburgh discovered that there's a difference in 11:04 the way brain cells die and men and women after injury once brain injury occurs glutathione remains stable and 11:11 females but has an upto of an eighty percent drop in males resulting in greater brain cell death this could also 11:18 be a contributing factor in the difference between overall longevity in men and women men are more likely to 11:24 perceive a neutral face as unfriendly during puberty vasopressin influences a boy's brain to perceive neutral faces as 11:30 unfriendly researchers in Maine gave a single dose of vasopressin two teenage years and found that the girls were more 11:36 likely to see neutral faces as friendly while the boys were more likely to interpret them as unfriendly or hostile 11:43 males are more likely to exhibit aggression physically while females are more likely to exhibit aggression 11:49 verbally this difference has been documented in almost all other mammals we used to tributed to testosterone but 11:55 now we know that it's because we've evolved to process anger different emails aggression pathways are more 12:01 directly connected to the brain areas for physical action I females aggression pathways are closer linked to her verbal 12:08 function males have a larger amygdala which is the Center for aggression females have a larger and faster 12:13 maturing prefrontal cortex which is responsible for inhibiting aggression males have a more active right amygdala 12:19 which is responsible for taking action and negative emotions females have a more active left amygdala which are 12:25 responsible for a more mental reaction than a physical reaction some men have 12:30 what is called autocatalytic anger which means that it is self reinforcing and 12:35 that it inhibits their fear and actually produces sensations of pleasure although most women are slower to act out of 12:42 anger once their verbal reaction starts it's hard to stop these brain 12:47 differences exist because they've helped our survival females are generally smaller than males so being and violent 12:53 towards someone twice your size is a great way to put an end to genetic legacy females are often vulnerable 12:58 because they're encumbered by pregnancy or infants so their survival has been contingent on their social group because 13:05 females have had to band together for their protection fighting other females is also a really risky thing to do 13:12 another reason why females have evolved the brain circuitry to prevent outbursts of anger is so that they're less likely 13:18 to hurt their children a male survival is linked to his rank dominance and power and these things even today can be 13:25 attained by physical confrontation but aggression isn't necessarily a bad thing men have been the valiant defenders of 13:33 their tribe their land and their family these things all need acts of violence if you're still unconvinced look at the 13:41 modern jungle the high school boys fight with their fists girls fight with das women use both sides of their brain to 13:47 respond to emotional experience while men just use once a study from Stanford showed that when a female was shown an 13:54 emotional image nine areas of her brain lit up versus only two in the male brain women are also better at retaining 14:00 memories that are emotional in nature women read subtle emotion better than men women recognize signs of sadness in 14:07 the face about ninety percent of the time while men only forty percent of the time this is probably why women involved 14:13 to cry four times more than men it's a visual display of sadness that will be obvious to any man a Stanford study may 14:20 have also indicated that little girls will recognize faked facial expressions better than little boys in terms of 14:26 evolution and makes sense for females to read facial cues better than males because they need to be able to 14:32 interpret the physical needs of nonverbal babies a male's brain circuits 14:37 will use more vasopressin and testosterone while the females will use more oxytocin and estrogen when you give 14:42 a man just one dose of oxytocin his ability to read subtle facial cues improves dramatically males and females 14:49 are not empathetic in the same way we have two motional systems the mirror neuron system and the temporoparietal 14:55 Junction system the MNS is responsible for emotional empathy it allows you to 15:00 feel what the other person is feeling the TPJ is responsible for cognitive empathy it actually allows you to 15:06 distance yourself from the person's emotions focusing instead on analytically solving the problem we see 15:12 this clash all the time a woman will tell from man of a problem she's having looking for emotional support but if he 15:18 is able to solve her problem he won't understand the point of having a lengthy conversation about it I males mirror 15:24 neuron system is also more fragile and can be stunted by pacifier use the most interesting study that indicates that 15:31 women are more emotionally empathetic was conducted at the Institute of neurology in London they tested couples 15:37 first the women were hooked up to a series of electric shocks then the men were given the same treatment it was 15:43 indicated to the woman when and what kind of shock was being administered to their partner and even though the 15:49 females couldn't hear or see their loved ones the same pain areas that lit up when they were getting the shocks 15:54 themselves lit up as they learned that their partners were subjected to the same treatment researchers were unable to duplicate 16:01 these results with males men thrive in conflict women avoid it females are more concerned with social approval and 16:08 preserving relationships men tend to get a positive chemical boost from conflict and competition while in women it 16:14 elicits a negative response if a woman feels that one of her close relationships is in trouble she may 16:19 experience a change in her serotonin and dopamine levels which will elicit a response on the similar spectrum as a 16:25 small seizure overall females have more brain circuitry dedicated to monitoring close relationships than men now don't 16:32 misunderstand me this isn't because girls are better human beings than boys or something this is an incredibly 16:37 powerful survival tactic it's even seen in other primates like baboons the female baboon with the most social 16:43 connectivity will have the most surviving young as I already mentioned in nature females are more vulnerable so 16:49 their survival depends on social ties men are aroused under stress while females are turned off men will get an 16:56 extra sexual kick when stress levels are high in fact they will actually bond better with females under an aggressive 17:02 or stressful environment by contrast a female is more likely to reject a male's advances in a stressful environment 17:08 cortisol blocks the reception of oxytocin and female brains shutting off her desire for physical touch and if a 17:14 woman does have sex under stress she will not be able to attain orgasm because her Magdala is active from an 17:20 evolutionary perspective this makes perfect sense if a female is stressed this is likely reaction to an unstable 17:26 environment under which getting pregnant is a terrible idea but for male a dangerous environment is actually an 17:31 incentive to try and procreate with as many women as possible because it increases the odds of his genetic 17:37 survival in tumultuous times men and women use different parts of the brain during sexual arousal women the 17:43 ventromedial hypothalamus and the cerebral cortex sexual experience and women is more connected with the rest of 17:49 what's going on in her head and the world around her men the hypothalamus specifically the medial preoptic area 17:55 and the amygdala the medial preoptic area guides the performance of sexuality 18:00 while the amygdala creates the motivation for sex this is probably why men are more likely than women to 18:06 conflate violence with sexual men are easier to sexually arouse than women the Center for sexual anxiety is 18:12 smaller and men than in women and as mentioned if the female amygdala is active she'll have a very hard time 18:18 getting aroused men are more motivated by sex than women men have double the brain space and processing power devoted 18:25 to sex this change starts as early as eight weeks after conception when testosterone cooks the fetus enlarging 18:31 the hypothalamus a second surge of testosterone hits during puberty strengthening the brain connections responsible for smell and touch teen 18:38 boys typically have three times the sex drive of girls of the same age a difference that usually persists into 18:43 adulthood a woman's libido decreases in the last two weeks of her cycle when progesterone is high this obviously 18:49 doesn't happen to men unless progesterone is administered which is what they do to sex offenders to 18:54 decrease impulses one study scanned the brains of men and women observing a natural scene of a male and female 19:01 having a conversation the men's sexual areas immediately lit up the women stood on a man's sexual fantasies are almost 19:07 purely visual while a woman's often include romance our orgasms affect us differently in females the dopamine and 19:14 oxytocin released after orgasm make her wanna cuddle and talk and men it's released into their hypothalamus which 19:20 triggers the sleep centers of the brain and the back arching response is strictly a female phenomenon the bed 19:26 nucleus of the stria terminalis holds a neurotransmitter that is twice the size in males than in females what's 19:32 interesting is that when transsexuals were studied postmortem the size of their neurotransmitter coincided with 19:39 the gender that they identified with this was true with transsexuals that did hormone therapy and it was also true 19:45 with those that did not that's all I'm saying because that's a rabbit hole of a topic men are attracted to youth and 19:51 beauty women are attracted to status David buss studied over 10,000 individuals from 37 cultures worldwide 19:57 and you found that there are universal preferences from both men and women when it comes to choosing a mate and these 20:03 preferences haven't changed since we became a species men want symmetrical young healthy looking and fertile a 20:10 man's visual cortex is pre-wired to notice the hourglass figure and it only takes a fifth of a second for a man to 20:16 classify a woman as high or not women want symmetrical generous trustworthy about three years older and 20:21 four inches taller they want high status signs that the man will invest in her and their offspring security and 20:28 resources or the potential for resources this is even true for females that are completely financially secure men want 20:35 high-pitched voices women want deep voices in a study of the African tribe called the hosta the men rated women 20:41 with the deep voices as better forgers but they wanted to sleep with the women with the high-pitched noises the women 20:48 rated the men with the D forces us better protectors and hunters and rated the men with the high voices as 20:54 unattractive men pursue women are pursued the quaintness of females and the sexual boldness of males seems to be 21:01 universe even in tribal cultures untouched by Western principles men do the wooing the reason for this is simple 21:07 eggs are expensive and sperm is cheap women are limited to the amount of offspring they can have because 21:13 pregnancy is physically costly and the time consuming investment men are only limited by the amount of women they can 21:19 sleep with in species where parental investment is more evenly distributed we see wound behavior from females for 21:26 example the male pipefish does the incubation of the eggs so we see a wound behavior from the females when a man is 21:32 in love dopamine mixes with testosterone and vasopressin when a female is in love and mixes with oxytocin and estrogen 21:40 contrary to popular belief it's men that fall in love with birth site a woman's brain is set up to be more cautious when 21:46 it comes to potential mates brain imaging studies revealed that when a woman is in love there's more activity in the brain areas that process memory 21:52 intuition and attention while men in love show more activity in the high-level visual processing areas 21:58 basically a female needs to carefully assess a man's survival and replication value which takes time this is why 22:04 pickup artists like to surround themselves with pretty girls the strategy is called pre-selection it signals to other females that this man 22:10 has already been vetted and approved a men on the other hand knows almost immediately if he would have offspring 22:16 with a woman based on her visual appearance this is why we have the beauty industry it's not driven by 22:21 patriarchy it's driven by a natural urge to want to attract high-value mate men are more comfortable lying to the 22:27 opposite sex when during the vocal strain of men and women lying to each other the men showed 22:32 significantly less strain this also made them more convincing liars high self-esteem makes teen girls less 22:38 promiscuous but it makes teen boys more promiscuous a man is more likely to sleep with a stranger than a woman many 22:44 studies confirm this for example an experiment done on college campuses showed that three-quarters of men that 22:50 were approached by random woman that offered them sex said yes when the reverse was done zero women agreed to 22:56 the casual sex when it comes to casual sex women care about intelligence men do not in a study where men and women were 23:03 asked about the minimal level of intelligence that they would accept in a person they were dating both said about 23:08 average when they were asked the minimal amount of intelligence they would accept in a person they would have sex with the 23:14 women said above average the men said below average men have a stronger reaction to physical infidelity while 23:21 women have a stronger reaction to emotional infidelity men will react with visible distress to the idea that their 23:28 mate is physically cheating on them the distress lessons of the cheating is purely emotional for women the total 23:34 opposite has been documented think about it if a woman seeks a man to invest time and resources into her and her offspring 23:41 the bigger threat lies and her maid becoming emotionally attached to another woman because it means that he may 23:47 abandon her a one-night stand isn't exactly a big threat to her stability for a man a risk of his mate being 23:54 impregnated with another man's child is the threat I know this sounds cruel and I'm speaking purely from biological 24:00 terms but for a man to invest in another man's child doesn't really help his 24:05 genetic success a man's fertility depends on who is 24:13 around him a man's sperm count will actually increase when he's away from his mate it will also rapidly replenish 24:20 if he's having sex with multiple partners but if the sex is with one woman his sperm count will actually 24:26 deplete with every copulation a woman's account stays the same from birth and no she does not keep ovulating if the 24:32 prevalence of young depre lads increases around her females are slower spatial tasks than males we're mentally rotating 24:40 three-dimensional objects females will get the answer right as often as males but it will take them longer this 24:46 difference is documented in both kids and adults and it is likely because the spatial movement area is an autopilot in 24:52 the male brain while it's on standby in the female brain waiting to be turned on females navigate using landmarks males 24:59 navigate using Cardinals and distance this difference emerges as early as five years old and it is probably because we 25:06 use completely different parts of the brain to navigate women use the cerebral cortex which is also used for understanding and interacting while men 25:13 use the hippocampus which is an area of the brain that is pre-wired for navigation we're in different schedules 25:19 around age of 12 testosterone receptors reset the boys clock cells this makes 25:24 them stay up and wake up about an hour later than girls of the same age men are more consistent than women men go 25:30 through several hormonal shifts during their life in the womb during adolescence through puberty as they 25:36 father a child and as they age women are constantly under the influence of their hormonal shifts and these changes are 25:42 much more intense than we'd like to think at the starter first cycle a woman will experience a twenty-five percent 25:48 growth in the connections of her hippocampus estrogen will stimulate brain function making girls relaxed and 25:54 sharp then during ovulation progesterone reverses the actions of estrogen and destroys the new connections during the 26:01 last week's of the cycle progesterone causes her brain to be sedated irritable and unfocused then progesterone 26:07 collapses leaving her brain sentimental sensitive stressed and even hostile this 26:13 can make a female act very different week it can augment and amputate parts of her 26:18 personality it can leave her swinging between interpretations of the world for example when her estrogen Peaks right 26:25 before elation she may feel incredible verbal intimacy and sex drive but when androgen peaks she may be prone to 26:31 outbursts another thing another very very sexist thing a woman's hormones may 26:37 bottom out right before her period and then not replenish fast enough this prevents a much-needed serotonin boosts 26:44 leaving her brain very irritable this is otherwise known as PMS and it happens to 26:49 ten percent of women a woman's brain is more flexible than a man's I had a very 26:56 special point in a woman's life her brain will experience a major restructuring her stress circuits will 27:02 become suppressed her cortex will enlarge and the rest of her brain will experience a shrinkage she won't lose 27:09 any brain cells but her pathways will change and new networks will form until her brain is back to normal size when 27:15 does this happen when babies this change starts during pregnancy completing a new mommy brain about six months after 27:22 delivery we have different reactions to crying babies mothers show greater activations in some brain areas than 27:29 fathers when they hear the crying of their infant you can get more details on that point in the written version of 27:34 this video which is on my website brave the world calm and it's all linked below mothers and fathers do not interact with 27:40 their children the same way we truly do complement each other mothers create stability Comfort nurture they encourage 27:47 reinforce and coddle fathers destabilize roughhouse challenge tease and stimulate 27:52 through unpredictability obviously none of these are mutually exclusive but you get the point researchers at the 27:58 University of Toronto found that mothers usually sing the correct versions of lullabies while father is like to mix it 28:04 up adding their own unpredictable versus I am the exception twinkle twinkle you 28:10 should rest you're the rig liest in my nest fathers tend to give the children 28:15 direct orders while mother's use shorter sentences and tone matching often having 28:20 no need for directness because they're so emotionally in tune with their children mothers get an oxytocin boost 28:25 after affectionate contact with their children while fathers get the was after exploratory play a perfect 28:32 example of this dichotomy is a study of one year olds at their swimming class it was noted that fathers were more likely 28:37 to stand behind their children so that they faced the water while mothers would stand in front of their children so that 28:44 they could make eye contact remember how we talked about females evolving to rely on social bonds for their survival 28:49 because of their smaller size to this day most women have lots of friendships which together act like an extensive 28:56 emotional support network a man's friendships are quite different they revolve around common interests 29:01 activities competition and work a man's significant other is often the only person outside of his immediate family 29:08 that's there to offer emotional support now pair that with men being way less 29:13 likely to seek help and you get a significantly larger suicide rate in males than females with single males 29:20 being the most likely demographic to take their own life in a warm touch 29:25 study researchers found that while both husbands and wives got a reduction in cortisol and a boost oxytocin only the 29:32 husband's got a reduction in blood pressure our culture likes to joke that married men die first to escape their 29:38 nagging wives but jokes a new culture because married men stay alive up to 1.7 29:44 years longer than single men men and women's brains age differently men lose more of their cortex and they lose it 29:50 faster than women also the volume of gray matter decreases faster in the aging male which may contribute to the 29:56 development of neuropsychiatric disorders like Parkinson's these are not hard rules but they are an important 30:03 insight into how we function and what motivates us they show that your sex does come with a blueprint that heavily 30:10 influences how you behave and how you view the world I strongly encourage discussion below and i'm sure this list 30:17 is not perfect i make videos it between my but that's why I made it so extensive 30:23 there's too many it's discount an innate real biological difference between the 30:28 sexes feel free to review any of
