Women's Brains Age More Slowly Than Men's : Shots - Health News : NPRResearchers say the metabolism of a woman's brain remains higher than a man's throughout a lifetime. And that may help with late-life creativity and learning.https://www.npr.org/sections/health-shots/2019/02/04/691356272/scans-show-womens-brains-remain-youthful-as-male-brains-wind-down
I think maybe you took my post more seriously than was intended.
Yes, of course this "research" was of little value and probably a waste of taxpayer money.
I could just have well have posted a clip about "research" where people were brain scanned while they orgasmed in a laboratory setting (see 1:10 in the clip below).
The "researchers" discovered, among other things, that women's orgasms last longer on average than men's, and that other functions of their brains shut down more completely during orgasm.
Science marches on.
Nah... your brain is like your muscles.
Exercise (as appropriate) improves them both.
Use it or lose it.
