Just five days in, our New Year's resolutions are still relatively fresh, including those that have to do with good health and exercise. And when it comes to exercise, more and more Americans are taking up one that can fairly be described as a real stretch, as Rita Braver reports in our Cover Story:

Yoga: it's practiced by millions of Americans who credit it with bringing them better health, physical fitness, and serenity.

And then there are those who see it differently . . .

"How many of you would like to stay here for an hour and twist yourself into agonizing positions, ultimately wrapping your leg around your head?" Alec Baldwin asked a crowd. "How many of you would rather come with me to the movies and eat a pizza?"

Yes, that's Alec Baldwin, the famously un-serene bad boy, who not long ago made headlines, again, when he got into an ugly scuffle with a photographer staking out his family.

When he spoke with Braver, just before that incident, he made no secret of the fact that his main interest in yoga isn't anger management; it's that his wife Hilaria is an instructor.

"When I came to her class the first time and watched her teach her class, all I wanted to do was, like, pour a glass of scotch and light a cigarette and just say, 'This is never happening,'" Baldwin said.

But Baldwin was there -- at least in body -- when his wife taught an unusual class right in the Smithsonian's Sackler Gallery in Washington, amid priceless works of art.
