America's Oldest Workers, still going strong

Retirement? Forget about it. These seniors keep working into their 90s, and some of them keep showing up at the office after they hit 100.

Tao Porchon-Lynch teaching a yoga class

• 91-year-old yoga instructor hard at work

Tao Porchon-Lynch learned yoga while growing up in India, in the former French colony of Pondicherry, but she didn't become an instructor until half a century later.

For much of her career, she danced, modeled and acted in India, France, England and California. She appeared in Hollywood movies and on television before landing a job with UniTel in the 1960s, establishing TV stations in India. "I was playing with life," she says. "There was so much to do and so little time to do it."

Porchon-Lynch has taught yoga since the 1970s and certified 400 other teachers. Until recently, she was able to suspend herself by her hands in the full-lotus and peacock positions before she broke her wrist. She's still a competitive ballroom dancer, despite undergoing hip replacement five years ago. "I'm not going to give up," Porchon-Lynch says. "I'm going to dance and do yoga for as long as I live."
