Hmmm, this one I might just win.
Age 2: Lymphangioma. Or that's what they tell me. Basically it was a lump on the side of my neck the side of a softball. Scared the bejesus out of my parents as it was not known if it was cancerous. 30-some stitches in the side of my neck and it still hurts when you press on it. Funny sidebar: couple weeks after surgery I was playing with a buddy about 2 years older than me. I have a drain for the fluid sticking out of my neck, he won't give me back one of my toys so I picked up a shovel and whacked him in the head. Brave, crazy or stupid but only 2.
Age 7: Going waaaaaay back in time here, but as kids, we only used to wear helmets playing hockey (no cages). Got whacked with a hockey stick across the nose. Out cold, blood all over the ice and they had to reset my nose. Still have a ridge from that.
Stitches? Virtually all sports related.
Chin 7 - split while playing volleyball.
Lip - 4 inside, 3 out - back of guys head into my lip - his fault.
Eyebrow - 4 - elbow playing basketball
Ruptured (and subsequently re-attached achilles tendon) in grade 10. That was just a pile of fun, but female sympathy compensated nicely.
Knee surgery in my 20's. Twice. Scraped the underside of the kneecap (grinding) once, removed damaged cartilage twice.
Late 20's had another lump removed from my leg. Doctors unsure of what it was (biopsy, CT, MRI all inconclusive) so they went in and removed the lump, mostly weird-ass deposition of fat. 14 staples in my quad and one of four quad muscles gone with it. Yippee.
Wisdom teeth done too, impacted, so in hospital.
Esophogael invasions? Twice, thus far. Once for a mysterious ailment that was in my esophagus in high school, preventing me from swallowing without major pain. Dropped from 165 (heh, the glory days) to 139 in about 8 days
Second one was when I was anemic for several months about 4 years ago. Looking for coeliac symptoms. Blood test had been positive, but biopsy was negative (whew!). Still no clue what the anemia came from but it's gone for now at least. It was, um, accompanied by it's reverse companion too
Do concussions count too? 4. The hockey stick. Once in basketball (last thing I remember after the really loud crack was a really low ooooooooh
from the crowd. Once while waterskiing. This was the advent of the wing on the keel fin. We (I) decided to see what effect on deceleration it would have. Lots. Whacked-face first into the water at 25-off, 36 mpg. Worked the rest of the day afterwards until the lifeguard at the sports club forced me to go to the hospital. Car accident. Go figure.
Broken wrist from falling wrong while playing badminton (D'oh).
That covers most things anyway.
