Yeah, I broke my arm, when I was six (I think).. From tripping over a football. Then I fractured my arm (I was about 8-9), my brother was showing a "karate move" and was holding my leg in the air, while I was hopping on one leg, I was like "Put me down!" He let go and I did a backflip and landed on it. THEN, I broke my arm again (I was 10) from balancing on the top of my couch, I fell and stuck my arm out to catch me, it held my and just popped.. And the weird thing was, it was always my left hand..
Ahh, memories..
