Why I don’t sleep with pillows?

My wife and I gave up on using pillows for more than 10 years.  Pillows just made no more sense to me.  In my way of thinking, as we should frame a house as straight as possible, should not our spine be also as straigh as possible.  As a desk jockey, I already spend most of my waking hours with my neck in flexion; it makes no sense to use my pillow to keep my neck in flexion all night long.  I used to have chronic ( many years) neck pain until one day my hospital physiotherapist taught me to do a full cervical extension exercise.  That and abandoning pillow usage have proven to eliminate neck pain for me for many years so far.
