The Body Rules First, there are three commonly understood elements in any face-to-face human communication: words, tone of voice, and body language
when you are delivering any kind of business presentation, while your intellectual content may be delivered entirely verbally, the nonverbal cues are more than 10 times as important in your audience perceiving your belief or conviction concerning that material.
“It is not what you say that matters but the manner in which you say it; there lies the secret of the ages.”
the words, sound, and body need to support one another.
