Just wondering about the age of the guys who don't use a harness. I was pretty, er, what's the politically correct term, knowledge and intelligence challenged? Anyway, I was pretty $tupid until I hit about 40, then all of a sudden I started thinking - "hey, I could fall out of this tree, and I don't want to hurt that bad (or be fed by a nurse's aid for the rest of my life)."

Asked in good humor, but still wondering...
