I'm 66 now and slowing down.
Right behind you just turning 65. FP softball in spring and summer,
VB in the winter the past couple years. No more running up and down the court; stand still and let the game come to you.
However, putting in 8 - 10 hour days for tournaments can be quite taxing.
Pay is less than SB, but frequent quads and tournaments gets you a lot more matches per season than you get games in a softball season.
