People Can Be Double Jointed

Everyone has had a childhood buddy who boasted about having two joints before showing off their incredible flexibility by wrapping their legs around their head. Even though it may appear completely out of the ordinary and unusual, most people experience this completely normally, and it has nothing to do with having extra joints.

Being double-jointed is an improbability in science, and these folks most likely merely have a lot of flexibility, a condition known as hypermobility. Instead of the joints themselves, the soft tissues around a flexible person's joints are frequently to blame for hypermobility.

Although having such high flexibility might be advantageous for sports, it can also be a sign of the painful benign joint hypermobility syndrome, or BJHS. Scientists are currently researching this in relation to dancers since hypermobility can also be a sign of instability, which requires a person to use more energy to be upright or stable.
