From the FB tape:
Do you know the theory of six hands? According to this theory, any two people on Earth are separated by only five levels of common acquaintances (respectively, six levels of connections). This means that specifically you, a simple resident of Kharkiv, are acquainted, for example, with singer Bill Gates by a maximum of 5 people. Or even less. Funny is it, right?

Yes, the singer Billy Gates is really funny)))
