how would you like to be a researcher who spends decades on a study of human beings and their behavior. One researcher in New Zealand monitored 1,000 children born in 1972 and 1973. He tracked them into adulthood, visiting them every 24 months in their homes. The subjects didn’t know why they were being studied, but the results are amazing. By age 26, about half of them were significantly overweight or obese. The key contributing factor was how much television the children watched. If they watched a lot of TV, they were almost certain to be obese. Diet and physical activity did not correlate at all. According to the International Journal of Obesity, children who watch a lot of TV tend to snack a lot and don’t get outside as much. So, by all means, don’t put TVs in your kids’ bedrooms. They’ll be more healthy because of it.
