Melbourne, April 24 : At 83, a yoga instructor is still bending over backwards to spread the benefits of the ancient Indian system.

Bette Calman, who has 40 years of teaching under her belt, is living proof that a lifetime''s dedication to yoga will keep you flexible.

While others her age complain about aches and pains, Calman, from Williamstown, southeast Australia, focuses on getting tough manoeuvres right.

"I''m proof that if you keep at it, you''ll get there. I can do more now than I could 50 years ago," the Daily Telegraph quoted Calman as saying.

"You''re never too old. The body is a remarkable instrument. It can stretch and stretch, and get better all the time. Forget age.

"Even a basic posture, or just going to a window and breathing deeply, can have big benefits," she added

She teaches up to 11 classes a week with no sign of stopping. (ANI)
