With a dangerous illness on “Let's Dance”: That's how risky it is for Tony Bauer to take part. At the age of eight, his small intestine twisted and died, which is why most of it was removed.

Bauer has to wear a special backpack that supplies him with infusions for up to 17 hours a day. “I just can’t make a mistake. Everything has to be germ-free,” says Bauer in the TV show.
