So many people adopt a pessimist point of view. The irony of this, is that a pessimistic view point becomes a self-fulfilling prophecy for a lousy, shorter life. Here's some information from an Aetna website (can't link since it is behind a secure log-in):
"Americans are living longer than ever. Over the past century, the average American lifespan has increased a whopping 27 years. What’s the secret to a long and healthy life?
Good genes help. You get them from your parents. And since you can't pick your parents, this avenue to a longer life is out of your control. Besides, the value of good genes is in question. New research from Yale University found that genes contribute only 25% to the length of your life. This seems to mean that other factors, such as health behaviors and mental health, play a role in longevity, too.
Yale study claims that a good attitude helps keep your heart pumping and your feet tapping an additional 7.6 years on average. An optimistic outlook adds more years to your life than low blood pressure (4 years or less), low cholesterol (4 years or less), a healthy weight (1 to 3 years) and regular exercise (1 to 3 years).
"These Are the Good Old Days"The Yale study suggests that people who believe negative stereotypes about growing old may face a reduced life expectancy. If you think old people are frail and sickly, you'll probably see yourself as frail and
sickly when you get old."
So all that exercising you do and healthy eating are negated by reading and believing the garbage from the media.
