Run for your life

A recent study of 18,000 men found that those who maintained the highest levels of aerobic fitness lived 8.7 years longer than the least fit guys. “We’ve all been told about the importance of aerobics in our daily lives, but this gives us the data to prove it,” says Ken Cooper, M.D., founder and director of the Cooper Institute for Aerobics Research, which conducted the study. To attain that top fitness category, Dr. Cooper recommends, run 2 miles in 20 minutes or less, four times a week.
