i usually do something that doesn't require a lot of brain power as a "cool down" from my mental workout. I go watch foxnews, read Palin's book, or take a shot of jack, and a puff of weed. They all have about the same mental requirements. <applause> Thank you thank you. No, you are all too kind.
On the subject of switching counts and indices, I find that it is similar to my high school and college theater days. memorizing lines and monologues, stage direction, voice inflection, emotive responses, and trying to make it look natural and unrehearsed. This is not unlike card counting in a casino. The personnel are your audience, and the counts and indices are your monologues, your responses to PC questions are improvs, or rehearsed kinetic dialogue. So for me, I can switch from hi opt to hi lo and the indices with maybe an hour of practice. I'm sure anyone can do it, if they put they're mind to it. It still blows me away to this day that I could memorize a whole 1.5 hour play within a few weeks, all while juggling classes, binge drinking, binge smoking, and binge girl having.
