Secret to Longevity: Genetics and Lifestyle

Q.    My friends and I were at coffee the other day and the topic of longevity came up. Half the group felt that genetics were responsible for a long life and the other half said they felt it was lifestyle. Who’s right? We’re all in our 80s so I think we’ve done pretty well attempting to figure out this mystery.

You can go back to your group with the news that everyone is correct. Both genetics and a healthy lifestyle are important to healthy aging. Two recent studies lend credence to both theories. New research by the Centers for Disease Control and Prevention (CDC) confirms what other studies have uncovered. If you want to live longer don’t smoke, eat healthy, exercise and drink alcohol moderately.

During the study period, people who engaged in all four healthy behaviors were 63 percent less likely to die early, compared with people who did not practice any of the behaviors. But people can live longer if they practice even just one of these healthy lifestyle behaviors, according to the CDC. Not smoking provided the most protection from dying from all of the causes examined.

People who engaged in all four healthy behaviors were: 

·         66 percent less likely to die early from cancer,

·         65 percent less likely to die early from cardiovascular disease, and

·         57 percent less likely to die early from other causes compared with people who did not engage in any of the healthy behaviors.

On the other hand, another recent study has revealed that people who live to 95 or older are no more virtuous than the rest of us in terms of their diet, exercise routine or smoking and drinking habits, according to research by the Albert Einstein College of Medicine of Yeshiva University, Bronx, N.Y. That group found that genes were an important indicator of longevity.

Overall, people with exceptional longevity did not have healthier habits than the comparison group in terms of body mass index (BMI), smoking, physical activity or diet, that research indicated.

Let the debate continue! Take these results back to your coffee klatch and you are sure to generate even more discussion.
