Try a round of golf.  Researchers from the Karolinska Institutet (Sweden) studied data collected on 300,000 Swedish golfers.  The team found that the death rate among golfers was 40% lower than that of the rest of the population, equating to an increased life expectancy of five years.  The longevity effect was found to be greatest for golfers from blue-collar occupations than those from white-collar professions.  Those golfers with the lowest handicap (ie the best golfers) were found to have the lowest death rates.

A round of golf gets people outside for a half-day and walking at a fast pace for several miles, the combined effect of which is good for overall physical health.  Golf also can be good for mental and psychological health, as golfers engage in positive social relationships both on and off the course.
