Bette Calman is a yoga instructor at age 83. She teaches as many as 11 classes a week and has no plans to retire. From News.com.au:
"Even a basic posture, or just going to a window and breathing deeply, can have big benefits.""Yoga instructor Bette Calman still going strong at 83" (Thanks, Tara McGinley!)
It's that spirit that has made Mrs Calman a legend. The author of three yoga books was a pioneer of the regime in Australia in the 1950s, ran yoga centres interstate for 33 years and made regular TV appearances in the 70s.
