Most of the things I can come up with involve avoiding physical harm, but that's depressing so how about these:
1) Have to speak in public.
2) Faint at a wedding - almost happened when I was my sister's bridesmaid, but I sucked it up. Damn corset was too tight.
3) Go to jail - unless it's on a Monopoly board.
4) Work in the food service industry. Waitressing GAAAAHHHHHH!
5) Damage someone else's property eg crash their car, burn their house down, etc. Because OOPS!
6) Get fired!
7) Kill somebody.
8) Live through a war.
9) See a ghost.
10) Get abducted by aliens - or anything else for that matter.
