HAVING TOO MANY FRIENDS

Here's news that didn't need an Oxford professor to prove -- we can handle only a limited number of friends in our life. No matter how many times we're "friended" on Facebook or reached by phone, Dr Robin Dunbar says the maximum number of meaningful friendships is 150. In the case of political and corporate leaders, the number drops to 7.

Dunbar, an evolutionary anthropologist, says that while technology can expand our reach, our brain's neocortex cannot. Which makes sense, even though dedicated Facebookers may argue.

However, perhaps there's another reason. Not the brain but the heart! As the Scarecrow learned, having a heart means being able to have it broken. So, just maybe it's our heart not our brain protecting us from too many friendships.

Something to think about when that screen or that phone doesn't light up...
