Life Extension: Life Expectancy

Life expectancy means the expected time remaining to live, and it can be calculated for any age. (Wikipedia, the free encyclopedia)

Life Extension Program: Life expectancy can be extended at any age through an integrated Life Extension program tailored to your needs and environment. This program needs to include:

• Proper Nutrition
• Proper Exercise
• Stress Management
• Mental Fitness (Mental Exercise, Mental Nutrition, Meditation, Positive Thoughts/Attitude)

It's been said that a man dies simply because he doesn't know how to live longer. Well, thank goodness for man's progress in the area of life extension.

We Are Living Longer

People are living longer these days. According to the Centers for Disease Control, in 1920 the average life expectancy was 54. Today, people can expect to live to 78.

Feel free to speculate about why - better food supply, better medical care, better hygiene or any number of other factors. It's not totally clear to scientists how they all add up. But what we do know is that studies are finding genetics don't tell the whole story when it comes to which diseases will likely kill us.

"There's a saying that genetics load the gun, but it's the environment that pulls the trigger," says Dr. David Fein, medical director at the Princeton Longevity Center, a clinic in Princeton, N.J., which focuses on quality of life and prolonging it. "You can have the gene for a certain disease, but it doesn't mean you're going to get it."

Take heed: Your lifestyle choices are very significant. While there is no way to ultimately defy death, that isn't an excuse to start indulging in vices and neglecting your health. There are plenty of ways to keep the grim reaper at bay - and many of these "secrets" result in an improved quality of life.

Change Your Attitude and Extend Your Life

If you really want to live longer, then start with your attitude. Your way of thinking not only improves your outlook on life, but also how long you actually live. In 2002, researchers at the Mayo Clinic in Rochester, Minn., found that optimistic people decreased their risk of early death by 50 percent compared with those who leaned more toward pessimism.

"The exact mechanism of how personality acts as a risk factor for early death or poorer health is unclear," says Dr. Toshihiko Maruta, the main investigator in the study. Most likely, it has to do with the fact that pessimists have an increased chance for future problems with their physical health, career achievements and emotional stress - particularly depression. "Yet another possibility could be more directly biological, like changes in the immune system," Maruta adds.

Besides looking through rosier-colored glasses, there other personality traits that can help us live longer, healthier lives. According to Dr. Howard Friedman, a psychologist at the University of California, Riverside, conscientiousness is related to mortality in a significant way. The Terman Life-Cycle Study, which ran from 1921 to 1991, examined an array of factors like personality, habits, social relations, education, physical activities and cause of death.

"Those low on adult conscientiousness died sooner," Friedman concluded. Conscientiousness does not mean looking both ways before crossing the street, it means looking both ways when the light turns green so you don't accidentally run down a slow-moving pedestrian. Beyond that, a conscientious person's long-living qualities probably have to do with the fact that they are predisposed to constructively reacting to emotional and social situations, and are more likely to create work and living environments that promote good health.

Health Factors for Life Extension

There are also more traditional practices that the aspiring centenarian can take. People should stop smoking, eat a balanced diet and maintain a healthy weight. While these may sound "nanny-ish," they are factors that cannot be overlooked. This might not sound like much fun, but it's a lot more fun than being dead.

Research shows that obesity, for example, contributes to a slew of medical conditions, including diabetes, heart disease and various cancers. So powerful are certain lifestyle choices that recommended diets along with maintenance of physical activity and appropriate body mass can, over time, reduce the incidence of cancer by 30 percent to 40 percent, according to the American Institute for Cancer Research.

Pets Improve Life Expectancy

Animal lovers will be happy to know that having a pet can add years to your life, as well. One of the first studies in this arena, which appeared in Public Health Reports in 1980, showed that the survival rates of heart-attack victims who had a pet were 28 percent higher than those of patients who didn't have an animal companion. "The health effects seem to be very real and by no means mystical," says Alan Beck, director of the Center for the Human-Animal Bond at Purdue University. "Contact with companion animals triggers a relaxation response," he says.

Rebecca Johnson, a professor of gerontological nursing at the University of Missouri, Columbia, showed that interaction with pets does, in fact, reduce levels of the stress hormone cortisol. The ability of companion pets to reduce our overall stress level probably accounts for most of their life-extending qualities. "For many people, pets also provide a reason to get moving," adds Johnson. How many people, after all, would actually get any exercise if it weren't for overenthusiastic dogs?

Quality of Life and Life Extension Go Hand in Hand

To many people, quality of life is equally as important as life span. It is a good thing, then, that many of the factors that can improve your longevity can also improve your quality of life. After all, who really wants to live forever when they can have a life that ended perfectly?
