I have this belief that everyone has a regular life "super power" - mine is that I can poop, whenever I want (or not poop when I don't want, I can hold it for just about forever). I developed this power back in high school, pooping immediately after school and before cross-country practice started. It was absolutely crucial during the two years I was a Peace Corps volunteer in the Dominican Republic.

My wife has never selected an avocado from the grocery store that wasn't absolutely perfect. That's her super power, and it has spoiled me and crippled my avocado-selecting confidence.
