This is great list I saw this morning in the article on Yahoo Lifestyle. Based on Mayo Clinic study, a person's outlook on life may not only improve longevity but quality of life, according to researchers. I think I pretty much covered most of the eight point below (well almost, there is some work to be done still).

Steps you can take to live longer:

1. Don't sleep too much. Sleeping more than eight hours per night can reduce life expectancy, according to a February 2002 study in the Archives of General Psychiatry. Night owls, however, should take note: researchers say that sleeping less than four hours also increases death rates. People who sleep between six and seven hours per night were shown to live the longest.

2. Stick to a low-calorie diet. A recent study by the National Institute on Aging found that a calorie-restricted diet led to decreased insulin levels and body temperature, both considered signs of longevity. A diet low in calories but high in nutrients also led to a drop in DNA damage.

3. Have more sex. Researchers say that having intimate sex makes you happier, better rested and less stressed, which in turn can lower blood pressure and protect against stroke and heart disease. A study published in the April 2004 Journal of the American Medical Association found that "high ejaculation frequency was related to decreased risk of total prostate cancer."

4. Get a pet. People who own pets, especially dogs, have been shown to be less stressed and require fewer visits to their physicians than non-owners. Survival rates for heart attack victims who had a pet were found to be 12 per cent longer than for those who did not have one, according to researcher Erica Friedmann. Pet owners have also been shown to have lower blood pressure and are less likely to be lonely or depressed. Another healthful benefit? Pet ownership stimulates exercise.

5. Quit smoking. Middle-aged men who are long-term, heavy smokers face twice the risk of developing more aggressive forms of prostate cancer than men who have never smoked, according to a study that appeared in the July 2003 issue of Cancer Epidemiology, Biomarkers and Prevention. And according to a recent study in the Archives of Gerontology and Geriatrics, cigarette smoking has been clearly linked to the most common causes of death in the elderly. "Smoking is -- for all but some exceptional subjects -- incompatible with successful aging and compromises life expectancy even in extreme longevity," the study states.

6. Manage your anger. A study led by the Johns Hopkins University School of Medicine in 2002 found that men who responded to stress with high levels of anger were over three times more likely to develop premature heart disease when compared to men who reported lower anger responses. Furthermore, because anger is associated with high blood pressure, they were over six times more likely to have a heart attack by the age of 55.

7. Eat your antioxidants. Found in foods such as blueberries, artichokes, beans, cinnamon and cloves, antioxidant molecules scavenge free radicals, compounds whose unstable chemical nature accelerates the effect of aging on the cells. Cellular damage contributes to an array of degenerative diseases, including atherosclerosis, Alzheimer's disease and cancer. Research shows that certain types of beans are among the best sources of antioxidants, while blueberries and other berries follow close behind.

8. Stop nagging. Married couples who engage in heated arguments are more likely to have health problems than those who do not, according to a study at the University of Utah. Based on 150 healthy, older married couples, researchers found that women who are hostile toward their husbands are more likely to have hardening of the arteries. Men who are controlling in their relations -- or are married to someone who is -- are more likely to have atherosclerosis, a very serious condition of the coronary arteries.
