Why children have more flexible joints than adult?

Answer 1

They have more flexible joints because the younger children are the less their bones and joints have formed. Because they are so unformed, the bones are also able to stretch. If you don't practice as you grow older the bones and joints form fully and grow stronger and you lose your flexibility. After this it is harder to become flexible. On the other hand because your bones and joints are not formed properly yet they not only are flexible but can also break easily and then heal quickly too. It's ironic. You can bend incredibly, but break easily, and then you heal easily.

Answer 2

This is a good question! Most of the joints of the new born are free and flexible. This helps for some overlapping of skull bones during the natural or normal delivery of the baby. The bones do not unite till they are fully grown. This normally happen by the age some where between 18 to 21 in normal course. The change is gradual one from childhood to adulthood. So the bones are more flexible in infant than teenager. Young children tend to fall down very often. Smaller height and flexible bones give them more protection in natural way.
