there is no place that is plumb(level) in nature except the surface of a glassy lake. and how does one sleep on the ground? with the slope starting at the head.
also, this is just another example of how getting well in a hospital is accomplished. the hydration from IV's, the Iodine slathered all over ones body before surgery, and now the inclination of the beds. it sure as hell aint the food(unless seen as a reason to fast!) or the drugs.
oh yes, the prayers and thoughts of those who love you. being sick just doesnt seem real to anyone else unless you are hospitalized.
