Man, I wish!!! I will be 71 September 24, and some days I feel it! I tend to get in about 4 or 5 hours from 7 am or so, 3 to 5 days a week, and call it a day. I carry several bottles of water and drink it all, otherwise I tend to get cramps pretty bad in the feet and hands, otherwise, I manage it. Like today, about 96 and humidity was about the same and all I could handle was two hours but I managed to get 15 wheats, a '42 quarter and a '44 nickel. Life is good!
