As you know, at the moment I'm obsessed with the "little stuff"—as I have called it here, the "last 98%," that is the heart of implementation-execution. Here, without comment, is another factoid—with which most of you are already familiar. Body language accounts for about 60% to 80% of so-called "verbal" communication. No surprise, women are muuuuuuuuuuuch better at reading body language than men.
My most recent source is the very readable (fun) The Definitive Book of Body Language by Allan and Barbara Pease. [They also authored another of my fun-but-serious favorites, Why Men Don't Listen and Women Can't Read Maps.]
