For injuries, I've always been a cautious soul. I've never broken a bone, gotten a cut that needed stitches, or had a serious burn. Just the usual scrapes, nicks, and scorches.
For sick, I had Bright's Disease (I don't think that name is used any more -- it's lumped under nephritis) when I was 7. Near total kidney shutdown. I missed five weeks of school, and one doctor told my mom to take me home and make me comfortable for what time I had left. Darn it, she got a second opinion, so I didn't get a life of leisure out of the deal. I did spend those five weeks in bed, and it was touch and go for a while I'm told.
