Not necessarily. Although non-double-jointed people find the flexibility of double-jointed people appalling, it is a natural occurrence. It is just an ability that you were born with that others don't have, and since others don't have it, they find anything that they don't have appalling and 'gross'.
Thus, being double-jointed is not gross, but a rather useful asset.
I believe he is, yes, in his thumb. Being double jointed in the thumb, myself, I can do the same :)
Arthritis
no
hypermobility. your welcome :)
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.
Usually people that are Asian, or come from Asia, are double jointed. But still, it's possible to have someone that is not Asian be double jointed?
nope im double jointed in all my fingers and i can do and its cool
Yes, Melina Perez is known for being double-jointed which allows her to perform unique maneuvers and flexibility in the wrestling ring.
Yes, you can unless you arm is bringing you pain, which rarely happens. I am double jointed from the shoulders down to my fingers and I find no problem. However, cases can be different so if it hurts, let your parents/guardian know and have them take you to a doctor. They will refer to being double jointed as hyperlaxity or being hypermobile, just to let you know.
