First of all, I don't think it should ever happen, I think that's more of my father's generation sort of manliness.

Talked my dad into a 60lb peak bow when he was looking, he could pull 70 prob or at least 65, but he's only getting older and doesn't shoot often, and 60lbs is plenty for NA game...

Personally I'd work up to whatever weight I wanted to shoot. People have to remember sitting in a cold stand for 4 or 8hrs before getting a shot, they have to pull that bow back. I saw a guy on tv say you should draw your bow once every hour to kinda keep that shoulder/arm warmed up.

Either way draw what you can, if you're in decent shape and shoot often no reason you can't really be any age drawing any reasonable weight.
