While I never had any falling accidents, and never broke a bone or had a sprain, I am incredibly clumsy and oblivious. I've hit my head with significant force probably over a 100 times. Once I had a fireplace spike pierce my skull.
Oh, and my mentally challenged cousin almost drowned me, too. I was around 13 or so? They pushed me underwater despite having floaties. I was under there long enough to blackout.
Two reasons why I mentally like 16 forever. x,x'
