Is double jointed real

Yes, technically, being double jointed is real, but the correct name for it is hypermobility or hyperlaxity, which is what doctors and other medical people will refer to it as. Look those Words up and you can discover a little more about being hypermobile. I am double jointed, and can do lots of weird things from my shoulders to my fingers, so it does make me angry to see somebody who says being double jointed isn't real. It is, but they may call it something else. It's all the same thing.
