As everyone else over sixty has pointed out part of being mature is just understanding that some things are better left to people younger and fitter. Or at the very least get help from someone younger. What on earth do you you have to prove, except to your own warped idea of what you think you should be able to do? I bet there is noone in your life saying you should be able to do this or that. In fact I expect people say, look at what that old guy (or girl) can do. Wow I hope I can be as agile/strong/able when I am the advanced age of over over sixty. I am not saying you are old and decrepit. Just that being older and understanding one's kinda obvious limitations has nothing to do with cding or gender and everything to do with an unrealistic self image. There is nothing wrong and a great deal of right with being old.
