At your age the chances are good that genuinely proven treatments for healthspan and lifespan will exist by the time aging starts to matter. Right now nothing has solid proof it slows aging in people, and because aging plays out over decades that proof and long-term safety data really count. Calorie restriction and certain nutrients or drugs extend life in animals, yet humans live much longer than most lab species and already pass reproductive age, which changes the picture.
I've spent considerable time studying compounds aimed at extending lifespan. Things like activating telomerase, lengthening telomeres, improving mitochondrial performance, adjusting immune responses, and clearing out old cells, among others. From both formal studies and personal accounts, there appear to be promising advantages in helping seniors fight the effects of getting older. What do others think about using these preventively or beginning yearly routines before turning thirty? Has anyone younger than that, or knows of stories or data for that age group, noticed real changes from such compounds? If so, what kind? Essentially, should one think about them for slowing aging or do they only seem useful for turning back the clock?
