Women's Brains Are 'Four Years Younger' Than Men's, Study Finds (theguardian.com)
Women's brains are nearly four years younger than men's, at least in how they burn fuel, according to scans performed by U.S. researchers. "Scientists found that healthy women have a 'metabolic brain age' that is persistently younger than men's of the same chronological age," reports The Guardian. "The difference is apparent from early adulthood and remains into old age." From the report: The finding suggests that changes in how the brain uses energy over a person's lifetime proceed more gradually in women than they do in men. While researchers are unsure of the medical consequences, it may help explain why women tend to stay mentally sharp for longer. "Brain metabolism changes with age but what we noticed is that a good deal of the variation we see is down to sex differences," said Marcus Raichle, a neurobiologist at Washington University school of medicine in St Louis. "If you look at how brain metabolism predicts a person's age, women come out looking about four years younger than they are."
The scientists used a brain scanning technique called positron emission tomography to measure the flow of oxygen and glucose in the brains of 121 women and 84 men aged 20 to 82. The scans revealed how sugar was being turned into energy in different parts of the volunteers' brains. To see how brain metabolism differed between the sexes, the researchers used a computer algorithm to predict people's ages based on brain metabolism as measured by the scans. First, the scientists taught it to predict men's ages from metabolism data gleaned from the male brain scans. The striking result came when the scientists fed metabolism data from the women into the same program. While the program estimated male ages accurately, it judged the women's brains to be, on average, 3.8 years younger than their real ages. "The scientists then flipped the analysis around," the report adds. "They trained the algorithm to predict women's ages from data garnered from their brain scans. This time, when they fed metabolism data from the men into the computer, it estimated them to be 2.4 years older than they were. The way male brains burned sugar made them seem older than female ones of the same age." The study has been published in the journal Proceedings of the National Academy of Sciences.

...they aren't used as much. ZING!
Did they bother to include race in their study?
When i was in grade school it was explained that science was about controlling for factors.
Brains do not burn sugar (nor does anything else in the hooman body). Digestive enzymes break down the sugars into glucose.
Women since time immemorial have had to raise children and extended family even well into their old age. Men, less so. My grandmother connected our family together like glue and still hosted all family get togethers until her death at age 96. My grandfather.. Eh, he couldn't give a damn about that stuff after about age 55.
Given these different roles, women have to stay sharper longer at least enough to play their parts. I'm sure if this was about who stays more skilled at chess or building chairs, men might fair better.
Scientific proof that men are more mature than women!
Boobs, fart, boobs, whatever.
When they came for the communists, I said "He's next door. Take him away. Goddam commies."
What is this? A BeauHD article about brains that doesn't involve scrambling people's brains with LSD or electroshock "therapy?"
Oh wait, there it is... Reading between the lines, the underlying subtext here is: Women's brains are better (younger) than men's. Just in time for the democrats to again attempt to elect a female US President in 2020... Libtard BeauHD strikes again!
Go to editor school already, BeauHD.
So a man tranny brain is 4 years older? or can they identify as having a younger brain.
Idea for tranny: identify as 'being attractive', even though you are clearly not. Make ppl also pretend you are attractive in addition to pretending yu are a woman.
You could also say that men's brains are 'Four Years Older' than women's. So by assuming men's brain's are the reference and women's are younger I suspect you will annoy some. Just saying...
If women are so smart how come most of them end up marrying men?
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
No Test for tranneys etc?
How dare they have racist findings! How soon til theyre fired?
Even though I was born a man, I feel like I should have been a woman. Therefore my brain must also be 4 years younger like all other women.
If I'm reading this right, an AI model of the male brain is being asked to interpret a female brain as a male brain, and then to predict the age of such a male brain, which comes out lower than the age of the female brain masquerading as a male brain.
AI algorithms are notorious for finding any manner of correlation. How do you correct for brain size differences (or anything else) in such a study?
However, I wouldn't discard this study outright if I were planning to undergo a cross-sex brain transplant sometime soon.
That they should not be allowed to vote until they are 22?
"Eve of Destruction", it's not just for old hippies anymore...
Why is that important?
Where are the woman demanding to meet/befriend/marry younger men?
Are any other factors also persistent, such as brain weight or volume?
Where's the research revealing men have superior bodies, it can't be women all the time?
This reads like an answer looking for a problem.
The scans revealed how sugar was being turned into energy in different parts of the volunteers' brains
Sugar ? My brain runs on beta-hydroxybutyrate, you insensitive clod.
This article utterly failed to account for trans and nonbinary! I'll pause here while you check your privilege(s). Also, I'm Vegan and do crossfit when I'm not riding my road bike in traffic.
So as a male I should get to retire earlier . It seems only fair. I must be really old because I actually learned cobol.
Women's brains are four years more immature than men's.
Seriously, this is one of those studies which has no real meaning whatsoever, and the spinning is just because these days its more popular to place woman as superior (the opposite spin is equally trivial).

I thought women and men were identical? I thought that you could decide that you're a woman or a man and that biology had no intrinsic determination. Does identifying as a woman make you mentally four years younger? Shouldn't scientists not even be studying differences between the sexes because it is sexist to do so?
That why women are marrying or come into a relationship with younger men.
Which is why no female chess player can beat the world's best male chess player. Which is why 99% of inventions are invented by men - normally WHITE men, of course...
Something urks me about the headline - the study does not say that "the brain is older". It only says "an individual’s brain appears metabolically younger or older than it should".
If my brain really were 4 years older than my girlfriend's of equal age, how come that my my jokes a lot more immature than hers??
it's a famous saying, but now it turns out to be part of the scientific evidence for the validity of the patriarchy.
[ducks and runs for cover with a smile]
Sorry, just could not resist in the age of nasty faminists and the Gillette (all men are toxic creeps) razor ad.
Marriage ages a man at least 4 years.
NT
Nevertheless, the population is regressing to the mean.
So the model of predicting age due to brain metabolism was based on men's brains.
Imagine attempting to get funding and publishing study city Negro brains age 10% faster than European brains. Or Oriental process math at two level above whites.
As long as the truth is PC correct, then you get funding and publishing and citations.
Usually PC correct being white males are horrid.
and the scientists just did not read the memo explaining this. I think for this serious but not grave act of oppression we shall remove their white privilege by castrating, taring and then hunting them to the city limits...
Simple, if you just use half a brain at a time then you can certainly last a long time.
Could this be why they don't seem to be capable of a mature life perspective?
