second thing is basically uh when when it comes to exhaustive exercise can you show me one person over 40 who continues to kill themselves with these with these sessions and thrives I don't know of a single such person they're all invariably young the people who do like the really really growing stuff their people in their 20s and 30s um and then the reason actually for them even for them is not ideal but actually they do derive some benefit for me why when you're younger and when you exert over when you're exerting yourself uh but the body wants to protect you from the catabolic effects of cortisol so it's producing a lot of pregnant women and DHEA in the adrenal cortex with over time with Asian basically there are three layers of the adrenal cortex Zona reticular fasciculata and glomerular list right one of them produces cortisol the other one Paris aldosterone and the third one produces DHEA the ones that produce aldosion and DHA aquify with age remaining only the cortisol so when you're getting older and when you exert yourself you will get all of the negative effects of stress but none of the beneficial effects of these anti-catabolic hormones which you're producing when you were younger so so that's why when I said like don't over exert yourself is that when you're young you don't care because the body has its means to protect you when you're getting older all these defensive mechanisms are starting to malfunction or are largely absent
