Homeless in Utah ease stress with tai chi

SALT LAKE CITY, Utah - On a quiet morning outside a library in Salt Lake City, about 70 people are kicking and slicing at the air as they practice the ancient martial art of tai chi.

The group moves uniformly, a silent army save for the gurgling noises of an artificial waterfall and the wind moving through blades of grass.

One man with a long, gray beard balances on his right leg with a ragged blanket draped over his shoulders. A barefoot woman wearing torn jeans does the exercises as a tiny dog circles around her legs.
