What if you could add 14 years to your life?

Researchers say four simple rules can help you live longer: don’t smoke, drink a moderate amount of alcohol, exercise regularly, and eating 5 fruits and vegetables a day.

Jim Sahli is 83 years old and says he has never been seriously ill. He swims regularly and enjoys eating healthy foods, such as fruits, vegetables and all kinds of fish.

New research out of the U.K. confirms that Sahli’s healthy choices do make a difference.

"One of the most difficult accomplishment of my life was to stop smoking," he said.

Providence nurse practitioner Gillian Rosicky says the four lifestyle habits outlined in the latest study support a wealth of other research like it.

"We've known these things for a long time," she said.

But if we know these things, why don't we do them?

"It's really hard to integrate into our daily lives,” Rosicky said. "We sit in front of a computer and drive our SUV's from place to place.

Her suggestion: start small.

Sahli advises finding a type of exercise that is enjoyable and making it part of a person’s lifestyle.

“We're not just talking about longevity. We're talking about quality of life and being healthy and fit and able to do the things that you want to when you are older,” Rosicky said.
