I was paintballing on Sunday, It was great untill the final round, I was shot twice in the left hand one right in my palm and the other hit my middle and pointer finger right on the nail, it was swollen very badly and hurt like a bitch!
But... when I got home and tryed to play my guitar, i cound only play with my index and pinky, making me want to learn right handed tapping all five of my right hand finger and three on my left, it was great, I learnd out of eager sympathy and was great after that first hour...!
