5. Name: Mark Zuckerberg

Position: Co-founder, CEO of Facebook

Weird Habit/Hobby: Zuckerberg’s is the strangest habit of all—the 27-year old has a diet regime now where he only eats animals if he’s personally killed them. Therefore , when he goes to restaurants and he can’t kill, he’s vegetarian.

Talk about weird! (and comparing his practice vaguely to a certain vampire saga starting with ‘T’ makes it feel weirder).  Apparently, this is one way he’s being responsible, since most people like eating meat, but don’t like thinking that it was once breathing, feeling animal.  This way, the CEO of the world’s largest social network argues he appreciates his food better.
