Human Brain Cannot Handle More than 150 Facebook Friends

               
This is interesting. You may be able to amass 1,500 friends on Facebook, but your brain cannot handle them. 

Humans' brains are capable of managing a maximum of only 150 friendships. Our neocortex -the part of the brain used for conscious thought and language- limits us to managing social circles of around 150 friends, no matter how sociable we are. Social cohesion begins to deteriorate as groups become larger.

This is what Robin Dunbar, professor of Evolutionary Anthropology at Oxford University, says after conducting a research.
