Those who drive a truck for a living spend endless hours on the road and if used fruitfully can be make those hours extremely productive. They can spend those hours learning anything from Socrates to Speaking Hebrew as they absorb Audio Books and then have the additionally hours to think about what they’ve learned. Of course they can’t take a written exam while driving but when you’re spending endless hours going straight on a highway you’re mind will absorb the information even better. Even if they don’t use audio books they will have a great deal of time to analyze music, sports, or political discussion that we who drive an hour or less back and forth from work are denied. So the next time you run into a truck driver realize that he might have a great deal more information then what hits the road.
