31,100. Slightly higher than the average for my age (27,808), but still seems mighty low given my career choice. Dang.
Also, Ebor's post reminded me that I broke my kneecap at the beginning of summer when I was 12 years old. When my grandfather heard about it, he sent me a very old, very heavy (hardback) desk dictionary from his office library at home (he was a medical doctor). I read the whole thing from cover to cover that summer, since I couldn't really go anywhere or do anything (a full leg cast, plus just generally being 12 years old, led to a lot of home-based boredom). Obviously I've forgotten most of it by now. Oh well.
