Bob Stewart, who will turn 99 this May, began taking supplements in 2000, when he was in his late 80s. The retired podiatrist is also a strong believer in keeping active. He takes exercise classes at least three times a week and participates in numerous community activities, including a local men's chorus.

At 95, Stewart broke two world records'in the running long jump and shot put'at the National Senior Olympic Games.

They'd asked what I'd taken, what helped me out and that was one of the main things I'd started with. I said you should get fresh flaxseed and grind it every morning and take it. The stores had a run on flaxseed.
Another thing that I went on is nattokinase. It comes from Japan and it's made from fermented soybeans.
