Brain Droppings - vol 9
Like, when I bang my shin I immediately grab my leg and (if it's not bleeding) rub it to make it feel better but would never want someone else to do either to my soon-to-be bruise.
No one knows for sure why we do this but one current theory is that when we unite two parts of the same body, we're giving increasing the coherence of the brain's body map. A.K.A. Giving more information to your brain (which is freaking out) about the level of damage and hurt.
Basically saying, "See! It's not so bad!" This theory is supported by other studies showing that people experienced less pain as soon as they were able to look at the injured spot. You don't get that extra info from someone else's touch and they may make the injury worse by touching it. Lastly, obviously, grabbing the damaged area may protect against further injury (if you're losing blood or something's biting you, etc).
