This is something that I have been thinking about for a while.
They are the thing on which we rest our heads every night, yet do we know where they came from? Why is it so difficult to sleep without pillows? I need two pillows, one is not quite enough, although I can just about manage (on a trip for example) with one if pushed.
I have a large foam rubber pillow and a softer cotton one, the springy foam rubber one sets a foundation and the cotton one goes on top.
How far back in history do we find references to them and why do none of the other primates need them.
I have heard of an old campers trick, where one scoops out a small hollow in the earth, just to fit the hips. It apparently guarantees a good nights sleep. Has anyone heard of this or used it. Was it a sort of precursor to a pillow?
Your pillow thoughts, please?
