that is all well and good but lets see baring unforseen accidents when you are 40 he will be sixty five when your 50 he will be 75. At fifty I was still quite the fellow and now 10 years later I have to work had and the body just won't cooperate take twice the work to get the same degree of fitness. It is a fact not a number, I am glad you are working out but I just have to wonder who will be hurt the most later.
