You did not have a category for "51 and way the hell over" so I chose the last one. I am 72, but I have the mind and body of at 50 year old. (Bev says a 50 year old Chevy pick up that has been driven hard)
I agree the pole should have other age brackets. I am curious to see home many folks are under 40 and in what brackets but there will be far more in the 60 and 70's age brackets. In a few years I'll also be out of these brackets.
