Does being fat make you dumb? Not necessarily, but researchers have found an “association” between obesity and thinking skills in people between 60 and 70 years old. HealthDay reports that researchers studying the body mass index and mental performance of 250 people found that those with the highest level of abdominal fat tended to have worse thinking skills than those with the least amount of abdominal fat. The good news? In ten years it won’t matter: there was no association between obesity and reduced mental skills among people older than 70. Read more from HealthDay.
