How to live a longer life

We'd all love to live long, happy and healthy lives - but few of us know the secrets to success.

But 88-year-old athlete Saul Moss is still going strong and he’s revealed a few tips to a study focusing on the health of older Australians.

Saul does weights, swims twice a week, target shoots, and has a Guiness World Record for oldest unassisted scuba diver. But he doesn’t feel 88.

“When I'm swimming or weight training or other activities I feel I'm only 40,” Saul Moss said.13.42.14

His motto is that you use it or lose it, and says every part of the body, even the mind has to have regular exercise.

Whilst, wife Joan knows what keeps him going.

In her 70s she still tap-dances, line-dances and does aerobics.

“I think we each push each other,” Joan Moss said.

Along with 250,000 Australians, they've confidentially given details about their health to the 45 And Up Study, which has helped hundreds of researchers answer questions about preventing disease.

Professor Emily Banks says the study has found that the longer you sit the more likely you're going to die in the next three years.

Banks also say that women who breast feed have a lower long term risk of diabetes than women who don't breast feed.

Ageing is booming and with a growing number of Australians over the age of 65, what researchers can learn from people like Saul will only become more important.
