I'd say the list is for 70 YO. At 50 I was only 3 years retired as a kart racer. Think motocross if you've never driven one in a race. My joints went away at 60. I learn the hard way and by being educated everyday at 63. I can't and won't live w/o sex even if it's possible! I get up every morning with a stiffy. Don't get to do much with it, but it's ready.
