A couple of drinks a day has been shown to improve quality of life, according to a new study. Researchers from Boston University School of Medicine studied more than 5,000 fifty-year-old subjects in Canada and had them evaluiate their overall happiness.

The reusults were then tracked and subjects were followed up for a perdiod of time. Overall the participants who were 'persistant moderate drinkers' showed the highest levels of quality of life.

The rate for women was no more than three drinks a day and no more than four a day for men. The quality of life was measured by the Health Utilities index which examines emotions, cognition, desterity and mobility.

Such factors when examined in middle aged patients showed those who drank moderately showed higher levels in quality of life evaluation than those who didn't drink at all.

The study states, "overall, this study shows a positive relation between regular moderate alcohol intake and quality of life in middle-aged adults."
