Human touch is a powerful language, says a study written about by Ben Carey of The New York Times. The story says a range of emotions can be shown, or triggered, by the most casual interactions, such as a slap on the back or a high-five.

Touch makes people feel better and even excel at things they do. I think back to that boss who often gave me an encouraging shoulder whack on deadline.  I probably worked harder in that job, or at least rose above the chaos with some success.  (I’m not talking about the creepy grabber-boss here, mind you.)

Read Carey’s story; he’s a fine reporter and always a strong writer. This time he slipped in a clever last paragraph, so pay attention.
