A 93-year-old yoga teacher continues to get up at 5 am to teach her students, despite having undergone a hip replacement surgery.

Apart from practicing yoga for over 70 years, Tao Porchon-Lynch also does the waltz, jitterbug, samba and cha cha cha in her spare time.

The former model and actress practiced yoga in her youth in India and moved to the US when she was in her early 30s. After a career in Hollywood movies and television, Porchon-Lynch began working with UniTel in the 1960s, establishing TV stations in India.

She has since been teaching yoga to students in India, France, and the USA for more than 45 years including certifying 400 other teachers.

"I do yoga before I go to bed and I do yoga with my students when I get up in the morning," the Daily Mail quoted her as saying.

"I'm up every morning at 5 o'clock and I usually go to bed around midnight," she said.

Following a total hip replacement when she was 84 years old, doctors said her flexibility would never be the same. But she proved them wrong, and has since taken up ballroom dancing.

"I'm very stubborn about it. When people say it can't be done, I have to do it. Its just a matter of putting your mind on it," Porchon-Lynch said.

The yogi also leads trips to India, where she estimates she has been at least 25 times.

"There's so much to learn and I just feel I don't have enough time to learn everything," she said.

"The greatest thrill that you can really have is to see someone who says I cant do it and show them they can," she added.

Porchon-Lynch has just published her first book, Reflections: The Yogic Journey Of Life.
