Oh, wow.  Let's see...no sunscreen...no seatbelts...played in the woods w/o supervision, rode my bike w/o a helmet and there was a place by the railroad tracks and reservoir (on a little bridge) where we would cross over the LIVE third rail, 
carrying our bikes! 

  I also dove into our above-ground swimming pool a zillion times BUT, one time, I held my arms differently and dove in and hit my HEAD on the BOTTOM!!!  I thought my head split in half!  Of course, since there was no blood and seemingly, nothing was broken, I didn't go to the doctor!! 

  I am paying BIG TIME now for that accident.  It caused spinal damage and I have advanced degenerative disk disease!  (But I didn't die!!)  Ahhh, good times...
