Ever thought about how long you may live?  I've thought about it, and how about to the ripe old age of 115?

If you ask 115-year-old Misao Okawa what the secret to a long life is, she'll probably tell you it's watching what you eat.

And she may be onto something.

With 50,000 people in Japan over the age of 100, they tend to have a healthy and portion-minded diet in common.

So what is this magic diet?

Well firstly, it contains about 25% less calories per day than ours.

It's also mostly vegetarian, with a little bit of fish thrown in for good measure.

So there ya have it ... eat like the Japanese and live forever! Well, almost, anyway ... (Yahoo Shine)
