Here's an interesting experiment where a series of strangers, two at a time, were asked to pose in affectionate stances for a photo. At first the people felt awkward, but after touching each other in that way using body language that suggested closeness and caring, most of them started to feel a change come over them. http://www.truth-code.com/2016/05/two-strangers-were-asked-to-pose-in.html
Wow!
Bonding behaviors in action. Powerful stuff. Shows us how important it is to get off of screens too.
