A pal of mine, now in his mid-80's, has just gone on yet another skiing holiday. Only a few years ago he started skydiving, and engages in other harzardous hobbies. He is one of the fittest people I know. At the other extreme, far to often I attend funerals of people my age or younger. Whilst there are many exceptions, in general, you are fitter and more active when you are younger.
