If you can lick your elbow easily, or touch your thumb to your forearm — congratulations, you’re among the minority of people. But some people bring flexibility to the next level. This condition is called hypermobility. It allows rare individuals to twist their bodies into weird positions just like a snake: putting their head between their feet, doing a back bridge, and all sorts of splits. But in some cases, hypermobility can increase sensitivity, because such people have a larger medulla. This brain area is responsible for processing emotions.
