Scientists have proven that 150 friends is the most that we can cope with. The obsession with adding new friends is bigger than you may think. Nearly 85% of us add friends we “think” we know or add even if we don’t know them just to make our friend lists seem bigger. Sad but very true.

Oxford University Professor Robin Dunbar has conducted a study of social groupings throughout the centuries, from neolithic villages to modern office environments.His findings are based on his ‘dunbar theory’ which asserts that size of the part of the brain used for conscious thought and language, limits us to managing 150 friends no matter how much we think we know!

Ever had a friend add you and you don’t know who they are? Keep adding you? Now there is a new function called “Mark you Don’t know” after choosing to “ignore” when you recieve the friend request. Facebook is testing out this new feature that lets you identify strangers who attempt to friend you, according to a report published today. Hopefully this will end the spammers out there who try to hack you too. Time will tell.
