how are your gps skills? we've never gotten around to getting one and now i may be glad. it seems that using a gps (using it a lot, i would guess) may turn your brain to mush.
three studies have been done which conclude that how we navigate around today may impact the way our brain functions as we age. the article talks about the spatial navigation strategy versus the stimulus-response strategy.
it also talks about grey matter and alzheimer's and the hippocampus, blah blah, but i found it interesting. it would be particularly telling if they did another study made up entirely of air traffic controllers. controllers use spatial reasoning a lot! and if that group had a smaller percentage of alzheimer's victims, you'd think the theory really had truth to it.
regardless, i enjoy using maps and envisioning routes, and finding my way around, and i don't care if i get lost. it's a quick way to learn about the vicinity. of course, the way that guys give directions and the way that gals give directions are completely different and worthy of a study by itself!
anyway, read the article -- it's food for thought.
