Ditch the GPS. It's ruining your brain.

164. Very interesting to say the least

For taxi drivers, delivery persons Etc who rely on a knowledge of traversing city streets, the training, such as the London taxi drivers driving around the city on mopeds for 3 or 4 years is a valuable asset and well worth it since their living depends upon it. I also acknowledge that the expanded memory gained from these exercises play into other aspects of their life as an asset.
What I would like to mention are the people whose livelihood does not depend upon a vast and comprehensive knowledge of the city streets in which they work. I offer delivery route drivers for example who take the same routes and stop at the same destinations on a daily basis, never varying from those routes. They would not drive the city streets on mopeds to learn the layout of an entire city just to learn a single route they would be taking on a daily basis. I would submit that there are probably exercises to increase the memory of those people with different occupations that require above-average recall as related to their occupation. Then there are those people who's livelihood does not require an above-average memory recall in order to perform their jobs well. I guess what I'm trying to say is that although taxi drivers have made the effort to increase their capacity for memory it does not automatically enhance their intelligence. That would all depend upon what if anything they have availed themselves with this asset. Maybe I DON'T know what I'm trying to say because......"THAT FREAKIN' GPS HAS FRIED MY BRAIN!!!!"
