Smile your way to 100

Longevity subject to lifestyle

Professor Richmond and her team studied 188 Australians who had made it to 100, and found that maintaining social networks, keeping physically and mentally active, and being open to change were common traits.

“About 20 to 30 per cent of the likelihood of living to 100 is because of your genes. But that leaves 70 to 80 per cent up to environmental factors,” Professor Richmond said.

“The major finding of this study is the impact of personality.”

Sounds a little dubious to me, but what do I know?
