Sleep is a wonderful thing

I don't think we give beds enough credit. Trust me...after spending two days this week trying to sleep on a bus seat, a bed is one of the most wonderful inventions i can think of. It is so amazing how one can feel like the walking dead for a day, then stretch out in a comfortable bed for a good 8 hours or so, and wake up feeling like a newborn.

What I find amazing is how one falls into specific patterns when they sleep. For instance, I can only sleep on my side. No matter how I try, and though I may doze off in another position, my real sleep only comes in a certain position with my arms in a certain place and only on my ancient double pillow. I wonder if that is a sign of an inflexible personality?
