Watching TV is GOOD for you?

 Previous research on the matter is mixed, but some studies found that eye movement can improve memory. Perhaps that explains why we found that people who watch more TV and read more have better memory and less dementia risk than those who do not.

While watching TV or reading, our eyes flick back and forth over the page and TV screen.

However, people who read often also tend to have been in education longer. Having had good education provides brain reserve capacity so that when connections in the brain are damaged, the negative result is less.
