"It is said that everyone can be linked within six degrees of separation. [x]"
as per Wikipedia....
Six degrees of separation is the theory that everyone and everything is six or fewer steps away, by way of introduction, from any other person in the world, so that a chain of "a friend of a friend" statements can be made to connect any two people in a maximum of six steps. It was originally set out by Frigyes Karinthy in 1929 and popularized by a 1990 play written by John Guare.
Proof that just 6 degrees of separation between us
A 'degree of separation' is a measure of social distance between people. You are one degree away from everyone you know, two degrees away from everyone they know, and so on.
