What Research is Trying to Tell Us

Do you really believe, like all the reports show, that the number one reason why we don't exercise is due to a lack of time? If you're racking your brain for a few more reasons to add more of an 8-letter word (EXERCISE, MOVEMENT, ACTIVITY) to your day, here are a few more reasons for you:
  • For every hour of TV you watch your life expectancy is reduced by 22 minutes.
  • For every cigarette you smoke your life expectancy is reduced by 11 minutes.
  • If you are watching 6 hours of TV a day your life expectancy will be 4 years less.
  • Highly active 65-years-olds add an additional 5.7 yrs of healthy life expectancy.
  • Men who were moderately active added 1.3 yrs to their lives and those who were highly active added 3.7 yrs. (
  • Women who were moderately active added 1.1 yrs to their lives and those were highly active added 3.2 yrs.
  • 15 minutes of physical activity a day reduces a person's risk of death by 14% and increases life expectancy by 3 yrs. compared with inactive people.
  • Researchers found if you increase the amount of calories you burn via physical exercise by 1000 calories, you reduce your risk of premature death by 20%.
  • Harvard alumni study, following close to 17,000 male alumni over a period of 22 years, estimated that subjects beginning and continuing to exercise throughout their life by the age of 35 to 39 years of age were able to add 1 to 2 years to their life, relative to those following a sedentary lifestyle (Paffenbarger, Hyde, Wing, and Hsieh, 1986).
  • Even starting exercise in mid-life may lower the risk of death by 23% over the next two decades.
  • In one study, those who exercised for an ave. of 92 min./wk. had a 14% overall reduced risk of mortality and a 10% reduced risk of cancer compared with people in the "inactive" group.
