i am 56, had a bad fall on my back. knocked my heart hard. had a hit to my right temple from a bolt building a bridge some time earlier that left me searching, forget full. the blood flow seems slow to my brain, I could hear it flow slow, my heart hurt for a long time also. my head pounds, my heart hammers, once after taking a asp. I could hear the blood flow creep to my head like some one with a hand pump very slow.
