I had a tooth removed, not a wisdom tooth, just a tooth. I freaked out, I was 12 or something. I wouldn't let the dentist do it in the chair, they had to put my fully under. Got a nice chunk of change from the tooth fairy.
There are people I'd be willing to donate to currently, at least partial donations ya know. One kidney, partial liver, etc. However, the need has, thankfully, never arisen.
When I die I'll donate whatever I can, help someone I don't know out, if my organs are worthwhile.
One question, how can you donate a brain?
