I got this toothache. It only hurts when I lay down. All day long, I'm fine. Come ten o'clock, I go to bed; it starts. It throbs all night long. It get up at five the following morning, and it stops.
Remember The Elephant Man? He couldn't lay down, lest he would die. (Something to do with is deformity that severely restricted his circulation.) Anyway, he slept sitting up.
Well, I thought maybe I can do it - sleeping sitting up...to avoid the pain. It might have worked. I didn't do it, though; didn't want to look foolish.
Isn't that something - how we fear looking foolish? Fear of embarrassment can be a great motivator.
Then we die. How foolish is that? We will be embarrassed in the end. (Death is embarrassing.) We're "found", usually in some awkward position. (Isn't dying bad enough? We have to be embarrassed, too?
The Elephant Man laid down, and died. Sitting up all night would not have killed me.
