Toe, The writes "Of particular concern to couch potatoes, gamers, and anyone who spends an inordinate amount of time sitting and staring at a screen is how little exercise can I do and still receive a benefit. A new study entitled 'Minimum amount of physical activity for reduced mortality and extended life expectancy: a prospective cohort study' answers this important question. The conclusion: 92 minutes of moderate activity a week can extend your life by three years."

    Actually, it's a net gain. If you work out 92 minutes a week, 52 weeks a year, for 50 years, you have spent 166 days working out and gained over 6-1/2 times that much life. What the summary doesn't inform us is how long before you die you have to start this regimen in order to get the full 3-year benefit, which could easily make that ratio quite a lot higher. Best-case, you only work out a little under 10 days during the extra 3 years.
