Sorry, Netflix fans. All that binge-watching could make your brain grow old before its time. A study in the online edition of JAMA Psychiatry looked at the television-viewing habits of more than 3,000 participants over a quarter-century — and the results don’t look good for folks who spend long hours in front of the screen.

The study authors point out that it’s not simply that TV shows are zapping your brain powers — it's the physical inactivity while you’re watching. “High television viewing and low physical activity in early adulthood were associated with worse midlife executive function and processing speed,” the study noted.
You’re also not putting your brain through its paces when you’re mindlessly following your favorite characters for hours at a time.
