It's a small thing I started doing years ago: whenever I see a loose nail or screw in the street I'll always pick it up and put it in the nearest trash so nobody gets a flat tire or steps on it. Small, but hopefully saves some potential misery for someone.
Highly developed sense of smell (sometimes a liability)
Ability to identify voice actors with high accuracy
