I did some googling myself Debbie on this subject. I will have to check out that quiz that you posted.

A dictionary definition of double-jointedness makes it clear: it is " having unusually flexible joints that can bend in unusual ways or to abnormally great extent."

Many people have a finger or arm that they can bend in an unusual way. This is quite common.


I didn't know that this was quite common. Oh well, I guess I will have to tell my son that he is just common. LOL!!!!

This is what my sister can do also.
