Daffuq?!

At the age of 15 Karelin broke his leg while training; having learned about this accident his mother
burned his wrestling uniform and forbade him to wrestle. Since then he broke his arms twice and ribs
thirteen times. Around January 1988 he had a serious concussion, and doctors considered removing
him from the 1988 Olympic team. Karelin won the 1993 World Championships despite breaking two
ribs in the opening bout against Matt Ghaffari. At the 1996 European Championships in Budapest, he
had torn the right chest muscle so badly that doctors predicted he would not be able to use his right
hand for several months. Karelin won the Championships, but had to be urgently operated on in Budapest.
He recovered within three months to compete at the 1996 Olympics.
