Childhood:
Around kindergarten age, I was jumping on furniture, missed, and slammed my head on a table. Then, the next day, we were playing horsey rides, I slipped off my friend and hit my head on a marble fireplace. The combination resulted in a loss of consciousness. Rushed to ER, slept through the CT scan, diagnosed with a concussion and finally woke up with some memory loss. I had to relearn the alphabet and simple math. They think I also forgot who some people were because I was very uncomfortable around some people I was once close to. I can't really remember anything other then laying on my parents sofa afterward and asking to dance and they said no.

~10yrs: Jumped to the monkey bars from some elevated bars and missed. Landed on my wrist and dislocated and broke a bone.

~15yrs: Dislocated my knee. Possibly the mose painful injury I have ever had.

Adulthood:
None thankfully! knock on wood
