Hmmmmmmm....can only speak as to how I feel but, for me, I don't want to be graded on the curve at any age or physical condition. As I grow older I'm well aware I can no longer do head flips or cross the parallel bars without sliding off and onto my fanny so I wouldn't even try. But I, also, know that I compete only against myself therefore, only I know how well I did a thing before. If I don't feel I measure up I just try harder or do it a different way the next time. For me, the absolute fun is in the doing of a thing, not what others think or how I measure up to them.
