George, Tony and Bill too...
BILL CLINTON: During his presidential speeches he frequently bit his lower lip, a gesture meant to convey sincerity and emotion.
TONY BLAIR: frequently raises his eyebrows as he speaks, a gesture that is the opposite of the lowered eyebrows typical of anger. "Raised eyebrows is a gesture of submissiveness. Tony often uses this to show he is agreeable."
GEORGE BUSH: adopts a "power walk", a swagger that conveys his influence and dominance, but when the pressure is on he begins to bite the inside of his mouth. These represent clear "non-verbal communication" that viewers can easily detect.
