Ways Technology Makes You Stupid
You cant find your way around without GPS
People who rely on GPS to get around have less activity in the hippocampus, an area of the brain involved in both memory and navigation, according to a series of studies presented in 2010. Using spatial memory which involves using visual cues to develop "cognitive maps" that remember routes instead of operating on GPSinduced autopilot can help avert memory problems later in life, the studies found.
A 2008 study from the University of London even found that taxi drivers had more developed hippocampi than nontaxi drivers perhaps because they are so accustomed to navigating cities using spatial memory, rather than relying on GPS (though that may no longer be true of smartphoneequipped taxi drivers).
