It is said that less than 2% of the population can actually lick their own elbow. Not sure if there is anything in Guinness’ Book of World Records on this. If we were to find someone out there that could lick both of their own elbows at the same time, then we’d have ourselves something.
So get to trying you just never know when you may figure out that you can inflict the condition of a double joint in on yourself by accident. I’m thinking I may of found #2 reason for needing a neck!
