peripheral vision.

This is what Warner (I think) was saying about books.  If you make them

too wide you have to move your eyes back and forth and that is both

slower and more tiring.

80-100 columns is fine, 132 is too wide, that forces people to move

their head/eyes back and forth.

Well, our physiology may be different.  I've got a 132 column window
open in front of me and I don't have to move my eyes side-to-side to
read.  I'm not seeing any of it via peripheral vision.
