The University of Leicester have found driving more than two hours a day lowers your IQ.
The study consisted of people ages 37 to 73 over a five year time period and discovered those who drove longer periods of time had their IQ scores drop faster for middle-age participants. Research also noted driving causes stress and fatigue, which effects the brain's function.
During the hours your driving, it also affects the brain because your mind remains less active during that time.
This could be bad news for some Angelenos since there are times when we spend that much time, if not more, in traffic!
