Need extra motivation to get to the gym or to go for a hike today? A study in the Archives of Internal Medicine followed over 2,000 twins for a year and discovered that the DNA of the active sibling (90 minutes of vigorous exercise a week) appeared four years younger than the DNA of the sedentary sibling.
So the May issue of Shape concludes that “for every minute you sweat it out per week, you can take about 16 days off your age.” Ok, let’s calculate this. Take the number of minutes you work out per week on average (say 3 hours a week or 180 minutes) and multiply that by 16 (days). Divide that number (2880 in this case) by 365 (days in a year) to find out how many years younger you are thanks to your active lifestyle. In this example it’s 7.89 years! Pretty impressive, but remember that in reality there are a bunch of other factors that affect aging as well. For a better calculation on how your good and bad health habits affect your age, take the Real Age test .
