Rick, that's a good way to describe it, and it's the reason I avoid traveling on the train during 'rush hour'. When people cross in front of me, or even come up beside me, I get discombobulated real fast! If they're moving too close to me, I freeze. Even on an empty sidewalk, if someone passes me and feels too close, I come to a stop.

I think our compensatory mechanisms work, but in a minimal way, so it's hard to do multiple things using the new circuits. I bet the new circuits can only handle so much, and then they crash, momentarily, when asked to do too much.
