Facebook friends: Why we should only have 150

Many people have over 1,000 friends on Facebook -- but experts say our brains can't cope with more than 150.

Academics from Oxford University claim humans are only capable of managing an active network of 150 friends.

This, says evolutionary anthropologist Prof Robin Dunbar, is the result of having lived for centuries in small tribes and villages.

He argues that while you may have over 1,000 friends on Facebook, you will only be able to maintain a worthwhile relationship with 150.

Then again, he could just be saying this to feel better about his own measly friend count and secretly wants more Facebook friends.
