Dry winter skin deserves attention for sure, but in some spas in China and South Korea, bathers are tossing out their loofahs and jumping in the tub with hundreds of little fish.

Nicknamed "doctor fish" or "nibble fish," the Garra Rufa can live off the dead cells of human skin, and also survive in steamy waters. Bathers take a soak in hot springs filled with the fish, and are said to only feel a tingling sensation while the tiny fish clear their dead skin away, leaving a fresh layer of healthy skin behind.

Even if the opportunity arose, I'm not sure I'd jump at the chance. What about you? Does this sound like a relaxing day at the spa, or does it make you think about being a contestant on Fear Factor?
