I have never had to be so cautious about my surroundings. The casino's sound like too much to bear. I live in D.C. And we used to go on the National Mall to see the fireworks. I can not fathom doing that now. The people, mass quantities of sweaty, possibly drunk people, loud noises and crowds on the metro....whoowwiiie, no way! But for you it seems like the challenge of working through an over stimulating situation creates those endorphins or something like them? Thanks for your post. It shows me friction may not always land me in the ER, but may lead to good days.
