Thai soldiers have covered their bodies with protective tattoos called Sak Yant for centuries. Many people believe they can't be hurt by a knife or gun in a place where the tattoo covers.

Sak Yant is an ancient ritual that's caught on in a big way with people around the world, from Hollywood types to American CEOs.

A Buddhist temple about 30 miles from Bangkok is one of the most popular, and most respected, locations to get a Sak Yant tattoo, because of its dozens of master artists.
