If you hope to live a long, healthy life, you may be surprised to learn that you can do so -- even if you don't exercise or eat well.
Florida woman Dorrie Aber-Noyek, who recently turned 104, is what scientists call a super-ager.
She lives independently, and once a week she even delivers mail at a memorial regional hospital.
At 104, most people are -- well -- dead. So what's kept Dorrie not just alive, but alive and thriving?
Dorrie says it hasn't been exercise or diet.
"Every day I eat cookies," she said. "Every day."
A new study reported in the journal of the American Geriatrics Society says what keeps super-agers like Dorrie alive so long seems to be their genes. The study looked at nearly 500 people, ages 95 to 112, and found their lifestyles were really no different than anybody else's. They had similar diets and similar exercise patterns. They were even just as likely to be overweight and drink alcohol.
All that makes sense to Dorrie -- her mother lived to be 99. Her daughter is 76, but looks much younger.
"I have some very good genes," Dorrie said.
So in the end, a genetic blessing seems to be the most important secret to an exceptionally long life.
