For me, I think the hardest part of that ten day event you speak of would be fighting my temptation to leave. That part seems challenging. I often wonder what it could be like to have even a few days where I'm cut off from anything that could interrupt my thought process. It's like a craving. To be the last survivor. I'd probably do ten days with ease if I was stranded on some island somewhere and can't waste time thinking about just walking away from it. I'm rambling. Oh well.
