Human brain limits friends to 150

A new study finds that the human brain automatically limits how many true friends you can have.
You may have Twitter followers that number in the hundreds and more Facebook friends than you know what to do with but a new study suggests that your brain has a limit to the number of people you can actually call true friends.
Back in early 90s, the British anthropologist Robin Dunbar began studying the social groups of various kinds of primates. Before long, he noticed something odd. Primates tend to maintain social contact with a limited number of individuals within their group. But here's the thing: primates with bigger brains tended to have a bigger circle of friends.

I first thought this thread said our brains limit a 150 character limit, I was like what? XD Interesting study, but I think this would be better linked up with facebook and myspace =/

In my opinion, there are some things science can't measure, and that includes the definition of the word "friend". People define friendship in different ways, and I believe there are people who genuinely believe they have more than 150 friends.

To me a friend is someone you do things with outside of work, like go fishing or hang out at a bar or go to a movie with or have over to your house for a bar-b-q. The people you work with are co-workers and anyone else is a neighbor or an acquaintance. By that definition most of us have very few real friends.

Its all about how good of a friend those people are, you're always better of with a few good friends that are like family instead of having hundreds who you aren't tight with. You can always rely on a few close friends.
