I really don't have an issue with my forearms, it's my hands. Most cooks don't have hair on their hands...'cause it's been burnt off. I'm a hairy guy, hands included but you can tell I'm right-handed as my left hand is hairy but my rightie is bald!
The coals seem to burn it off as fast as it grows!
But if you bake a lot I could see where this could be useful.
