when is it time to quit

[MaryN]

Well, personally, as a "mere" female, I don't do quitting! If I hung up my gardening gloves, fork, dog lead and horse halter, the place would probably grind to a halt. I'm not sure that training and exercising as such are going to do much for you in those later years. I was never into gym stuff and all that jogging (far too hard on the boobs!) but I try to keep fit by staying active as much as I can.

By the way, Dev, that Fighting book is tremendous fun!
