I think that is somewhat true, but, in reality isn't true. We basically age the same way, however, men seem to be far more shallow about the looks of women and more so with youth. I have aged fairly well as far as how my external body is concerned, and if I shave my beard off, I know I look younger than I am, but I'm too old to give a damn. I strive to be comfortable and no longer make any attempt to impress others. I am a strong advocate of relax and "just be you"! That doesn't mean just let yourself go.
My dad retired and decided that retirement meant sit and look out the window. He died when he was my age of a heart attack. My mom fought aging tooth and nail and lived to 87. She remained active, watched her diet, socialized a lot (meaning bus trips to casinos) and dyed the hell out of her hair which was amusing but to be truthful after someone is in their mid-80's you aren't kidding anyone. It ranks right up there with the comb over. I recently have been plagued by back issues which have clearly diminish my mobility. It is tempting to just give up and accept the condition, (somewhat connected with aging) but I have no intention of giving up yet. One surgery down, one more to go and hope to be close to my old self again, but whatever I do, I do to make myself feel better and I do not even a little care what others might think of how I look.
