hmm as a kid I once picked up a light bulb taken out of the ceiling light socket when my brother was changing the light bulb. He told me not to pick it up because it was hot but being no older than 5 I immediately picked it up by the metal cap. I have burn scars to this day on the tips of my fingers (the tips bubble out a little from where the blisters were) Stupidly though my older (yes older) sister decided that I couldn't possibly have been right with my screaming and crying about the heat and repeated what I just did... I never saw my sister as clever again after that.

I once cut my thumb open on a hegma-saw (sp??) in wood working class and shouted a torrent of abuse because I had bled all over the project I had spent 60+ hours preparing to be cut (the entire project had been using a belt sander, I hardly had finger tips or knuckles left I sanded them away with the wood.) My teacher thought I needed stitches I merely washed the cut and sucked on it a while, after doing so I noticed that the skin had been cut at a perfect 45 degree angle, so I simply pushed the top part under the bottom part and it stopped bleeding. I have a little scar but no infection and no stitches.
