Adding to my previous observations about my brain: I can’t abide sans-serif fonts. That is, they’re OK for two-word billboards (“Got Milk?”), but for document length reading they are intolerable. The fact that Microsoft made Calibri the default font in Word seems to me insanity.
But I’ve come to realize that most of the world is OK with sans-serif fonts. So I begin to wonder whether it is rooted in whatever causes my inability to handle small print.
