I almost died while my mom was in labor. It's this great story that ends with my grandmother throwing the new intern doctor person out of the room and making someone call in a "real doctor", who arrives and gives her a death glare, then looks at a bunch of monitors and performs an emergency c-section on my mom to get me out. They thought I would die, but I didn't. Then they thought something would be wrong with my heart, but my heart was and is fine.
I had a seizure once, on the first day of 5th grade. It wasn't near-death of course, and it never happened again, but it really freaked out my mother.
