I've nearly drowned
fell from my grandma's house's rooftop twice (≈2nd story fall)
ladder broke under me and I fell on concrete from ≈2.5m and then a huge girder fell on top of me
irradiated my face while building an X-Ray generator (skin came off; also, nice tan)
burnt my feet (both, stepped on some ember while barefoot)
bitten by dogs (3 times)
almost mauled by a bear
ran over by cars (3 times)
a skateboarding accident almost left me with my balls crushed (!)
I blame most of those on my stupidity though.
