Chad Kagy broke his neck in 2004. He had surgery to put a plate in his neck to hold together some vertebrae, and to do the procedure they had to cut through all the muscles in the back of his neck. It was a long, rough recovery, so the fact that he considered riding a bike again is pretty amazing. He went on to win an X Games gold medal a couple years later. Throughout his recovery he wore this neck brace.  He couldn’t really shave very easily, so most of the time he had itchy scruff, and he spent a lot of time itching. This photo captured that whole period of recovery to me.
