Yes, and that's why I still lift weights, just not as heavy as when I was 19, but more repeitions in each set.
I do know why most fat old men race monohulls though and there have been times I thought they were the smarter ones! I'm on my way out the door to sail some more this afternoon, good wind and the boat is rigged and ready.
Yesterday I tried a new (to me) rig for pulling the boards up, I finally got around to tieing a line between them and it worked great! I can set the spin, pull both boards half way up and be gone downwind very quickly now. And, as a bonus, if I did flip and one of the boards flew out of the slot (like happened once) it is tied to the other and the line goes under the footstraps so it can't float away.
