You're so sensitive. He was oppositional first. Anyone can keep something up for a while. Eventually it builds up. In the case of running, you get knee problems, foot problems, and shin splints. If I only had a dime for everyone who's said, "You're lucky. I can't run anymore!" I'd have, well, several dollars. You're right, I don't have a monopoly. Go ahead and offer your own. Do you have some?
