content: Man, I feel your pain. I tell people that my biggest problem is that I'm paying attention to everything.  I intake so much information, that I'm pretty mentally fatigued if I'm out of the house for a while.  My wife says "Just zone it out", but it's impossible.  I can't.  Almost nothing is "background noise". That plus tinnitus makes trying to sleep an utter nightmare. On the plus side, I haven't been in an automobile accident in 17 years.
