I post in this section, maybe it will be good for my question.
I wanted to ask why is there "over 35" section on most forums? Is that some "border" age between "young" and "old" in terms of bodybuilding, weghtlifting and overall fitness?
Could you tell at what age man starts to feel effects of aging, lowering testo etc?
I am not speaking about some serious effects, but when do you start (if ever) to notice any negative difference comparing to the time when you were in early or middle 20's (in terms of physical shape, fitness, maybe sex, looks and so)
p.s. i know that there are a lot of guys at age 70 and so, and still working out, looking & feeling good, but i wanted to ask about general tendencies in human body.
