How to Become a ‘Superager’
"Many labs have observed that these critical brain regions increase in activity when people perform difficult tasks, whether the effort is physical or mental. You can therefore help keep these regions thick and healthy through vigorous exercise and bouts of strenuous mental effort."Woah woah woah there. That doesn't follow at all. Even if you buy the "exercise model" - which can't possibly be tested by observing brain activity over minutes, since improvement would happen over weeks to months - that doesn't imply an ability to ward off old age over decades. In the case of literal muscle exercise, for example, playing pro sports will certainly strengthen your muscles now but likely cause long-term injuries. https://journalistsresource.org/studies/society/public-healt...
