Your friend is trying to convince you that if the ligaments binding the bones together at your freely movable joints (such as your knee, shoulder, and hip joints) contained a higher percentage of elastic fibers, you would be much more flexible. Is this true? If so, would this present any serious problems?

Yes, ligaments that are more elastic (or stretchy) will provide greater flexibility, but at the expense of joint stability. The joints would be prone to misalignment and dislocation.
