When I was about 2 and a half years old, I had chickenpox, but the infection never broke onto my skin, but rather infected the inside of my leg. I was in the hospital for 3 weeks as a result and there was talk of amputation and even concern that the infection could become fatal.
Thankfully, I pulled through OK. Kept my leg, got out of the hospital fine, and I was so young when it happened that I don't even remember it, so that's a plus.
my cousin rolled her bronco on the highway goin 70 on the way back from a concert with me in the back seat when I was 18... the thing rolled 5 times before we hit a rail and slid to a stop. cops were amazed nobody was dead when they showed up... my cousin nèeded stitches in her domepiece,but that was about it.... I was just scared the thing was going to blow up.
