Why Are Some People Double-Jointed?

The video explains the concept of being 'double jointed,' which is technically known as hypermobility. It clarifies that no one has double the number of joints, but some people have more flexible joints due to shallower joint sockets, elastic cartilage, or flexible ligaments. Hypermobility can be genetic, with conditions like Ehlers Danlos Syndrome causing unusually loose joints. While hypermobility can be a neat party trick, it has downsides, such as increased risk of joint dislocation and other health issues.
