Dont look if you are sensitive to blood... My lovely husband came walking in last Thursday from training for his triatholon.. and well.. his chain fell off his bike while down shifting and he fell and scrapped up his whole body.. this is the back of his leg... he thought he was just fine, well he ended up with 9 stitches and a nasty looking scar. I guess it could of been worse. He likes to tell people he got bit by a shark...(he thinks that sounds cool) I like to tell people he got bit by a dog! lol
