I have found two things since I started immersing myself in math:
1) I have a much better sense of direction. Not in absolute direction (i.e. whether I'm facing West), but in generating a mental map of my environment and not getting lost. I used to lose my car in parking lots all the time. Not any more!
2) I am far less eloquent in social contexts. While I used to be gregarious (and dare I say charming?) I now frequently find myself starting sentences and then not being able to remember the words I planned on using. And if I do remember the words, they come out stilted, without color or flow.
Is it just me? A non-causal coincidence? Or does this sound familiar to anyone else? If so, is it a temporary effect as my brain adjusts to a new way of thinking, or am I looking at a life of increasing social awkwardness and stellar navigational skills?
Note- also, I'm female. Traditionally, males have been deemed better at navigation, and women more fluid with words. This is supported by Psychology. Could math be "masculinifying" my brain? (I don't mean that to imply that math prowess is a masculine trait, just the side effects.)
Feel free to close this question if it's too soft or discussion-y -- but I'm quite curious.
