O'Reilly had a communications specialist on tonite, the night after the first Presidential debate. She reminded me of something very interesting about human communication (they were talking about how Dubya was looking annoyed, etc. when Kerry was running him down):
55 % Body Language
38 % Tone of Voice
7 % words
Your body language and tone of voice account for NINETY THREE PERCENT of what you communicate. Your words - what you are actually saying - only 7%. Think about it.
