Some might, then others might think about the numbers of "old boys" who came from an era when nobody even thought about testing, and lived to a ripe old age. Nothing is certain, except the quote I once heard "There is a simple answer to every problem, which is usually wrong".
All sorts of things play into the health question, genetics being one, how well you treated your body when young (exercise, lifestyle), and how you looked after yourself when older, how happy you were, how much mental stress, it goes on and on. I don't defend the PED use, but it's not the be all and end all of wht happens in later life.
In my own case despite not turning a pedal in anger for years, I'm lucky to have a low pulse rate (upper 40's low
50's), low blood pressure, heamatocrit around the high 40's, excellent lung function. Am I fit? I don't think so! Then my genetics suggest a life span around 80+ years, and some of those "old boys" who "prepared" themselves with all kinds of exotic cocktails (documented in historical writings), lived into their 90's, others passed on in the 60's and
70's. The genetic roulette wheel has much to answer for.
