Will live forever, but why? |
The very old are, in fact, no more virtuous than the general population when it comes to shunning bad health habits, leaving researchers to conclude that their genes are mostly responsible for their remarkable longevity.
But before you fall off the wagon and start tossing down doughnuts for breakfast just because your Aunt Edna just turned 102, remember that genetics is a game of chance. What didn't kill Aunt Edna still could kill you prematurely, the researchers cautioned.About 1 in 4,400 Americans lives to age 100, according to 2010 census data. I'm going to submit my name to be in that group.
The living, old people in the study were remarkably ordinary in their lifestyles, Barzilai said. By and large, they weren't vegetarians, vitamin-pill-poppers or health freaks. Their profiles nearly matched that of the control group in terms of the percentage who were overweight, exercised (or didn't exercise), or smoked. One woman, at age 107, smoked for over 90 years.
Whatever killed the control group — cardiovascular disease, cancer and other diseases clearly associated with lifestyle choices — somehow didn't kill them. "Their genes protected them," a researcher said.Taking the fun out of everything, the researchers said that for the general population, there is a preponderance of evidence that diet and exercise can postpone or ward off chronic disease and extend life. Many studies on Seventh Day Adventists — with their limited consumption of alcohol, tobacco and meat — attribute upward of 10 extra years of life as a result of lifestyle choices.
Well, poo poo pi doo on you, research Nazis.
