I can do this when I get home currently shopping for black Friday <| sep |> it ' s my coin <| sep |> I ' ve been concussed 4 times to varying degrees . The worst one was on a crack back block my senior year of high school . I never saw it coming . The plus is I don ' t remember any type of pain . I just completely blacked out . Next thing I remember is about 6 hours later at a hospital . Apparently I finished the game there was only about 2 minutes left . And just wandered around after the game . My buddy found me , they found my dad in the stands , and he took me to a hospital . I was kept there over night because I kept trying to fall asleep . <| sep |> i thought it was wifi at first . <| sep |> When someone flatlines you don ' t shock them ! A defribrilator shocky things causes asystoleflatline for a split second so the heart can reset itself to a regular rhythm . If the heart is already in asystole then you can ' t shock them into further asystole ! So on screen when they ' re trying to be all dramatic and shock someone ' s heart back to life after they ' ve flatlined , they ' re actually doing nothing in reality .
