A: 2 hours sitting in your car
According to a new study, spending two hours a day or more in the car makes you DUMBER. It reduces your IQ sitting in the car that much.
The researchers say driving is mentally stressful and fatiguing, and when you pair that with being sedentary for so long, it causes gradual declines in your brain.
(That’s not the only story about cars and intelligence that came out this weekend. Another study found that smarter people are more likely to fail their driving test the first time they take it.)
