Yoga instructor Bette Calman may be 83, but she’s still bending over backwards to spread the benefits of the ancient Indian discipline.

With 40 years of teaching under her belt, the Australian wonder is living proof that a lifetime’s dedication to yoga will keep you flexible as a rubber band.

So when will she give it up? 
‘You’re never too old. The body is a remarkable instrument.
‘It can stretch and stretch, and get better all the time. Forget age,’ said Mrs Calman, the author of three yoga books including one called Yoga for Arthritis.
‘Even a basic posture, or just going to a window and breathing deeply, can have big benefits.’
It’s that spirit that has made Mrs Calman a legend.

She was a pioneer of the regime in Australia in the 1950s, ran yoga centres for 33 years and made regular TV appearances in the 70s.
