Hide Their Phones & Laptops
Mamas, don't let your daughters grow up without exercising. That's the advice from researchers at the Vanderbilt-Ingram Cancer Center in Nashville, who analyzed the health records of almost 75,000 women ages 40 to 70 and found that those who reported having engaged in exercise as teenagers significantly cut their risk of early death later in life compared to non-exercisers. Specifically, women who exercised regularly each week when they were 16 to 19 years old ran a 16 percent lower risk of dying from cancer as middle-aged adults or older, and a 20 percent lower risk if they still exercised. There were similarly reduced rates of death from all causes. The study did not distinguish between types of exercise, and found that survival benefits seemed to peak at 80 minutes per week.
Less Boozing, More Car Texting
The new CDC report on U.S. teen behavior, issued every two years beginning in 1991, reflects both healthy and unhealthy trends. Cigarette smoking is down, from over 27 percent originally to under 16 percent now, but marijuana smoking has replaced it, up from 15 percent then to 23 percent today. Most other forms of drug use are down, as are the number of teen alcohol drinkers, now at 35 percent. But far too many teens, 41 percent, continue to text or email while driving, although more teens now use seat belts and bicycle helmets. Unfortunately, the number who spend more than three hours a day glued to a computer, game console, smartphone or other screen has spiked from 31 to 41 percent just since 2011. Overall, the CDC rates teen behavior healthier than it was 20 years ago.
