I think the reason the Partnership for a Drug Free America never did a commercial about your brain on technology is because it would make putting your brain on drugs look like a walk in the park.
A walk in the park, that is, without an MP3 player, a GPS, or a Smart Phone that is watching Facebook and Twitter updates. A walk without those things is fun. A walk with those things will do things to your brain.
Which brings me full circle. :)
I have neither and MP3 player, a GPS, nor a SmartPhone, so my wobbly brane is from something else.
And I cancelled my facebook account, and don’t pay much attention to twitter...they both seem like time wasters.
When I walk, I hear only the voices in my head, which tell me what to do and say... ;o]
