At first glance, someone would easily do a double take, while looking at these people. One can’t help but think this isn’t real, however it is real. There are no tricks here. They are simply known as head spinners, these folks have a rather unique ability. They can turn their heads 180° degrees. Imagine being able to see behind you and what is really going on—even if it was only for a few moments.
It is rather uncommon, to see someone contort themselves in such a way—by dislocating their bones in various different places. If someone were to do this for long periods of time, they would pass out from the lack of blood and oxygen to the brain.
The most popular method to this madness, is when someone turns their head like this to gain attention. There seems to be different reactions from this, either some people enjoy seeing this or equally so, they are grossed out by it. This kind of stunt, can even become a realistic nightmare for some.
Normally, the muscle in the neck prevents someone to turn there head in such a way like this. But with some folks like Alexander (seen in this clip) he is able to move his head like this as well. Doctors have been baffled about this for years and more research has continued about these extremely rare individuals.
