Learning Side by Side

I knew there was something to this social network thing I participate in.  Elizabeth Landau of CNN wrote an article called Happiness is contagious in social networks.  It essentially states that someone who is happy in a social network makes others happy.  And a happy face in a Facebook profile picture attracts other smiling friends to that person.  According to the following video, your health is also affected positively by the gift of happiness.

I was concerned that I may need to unfriend my Facebook and Twitter friends with profile pictures that don’t smile, but apparently I just have to make sure I have an exponentionally higher number of happy people to bring my own joy meter up.  Anyways, it’s time to spread some cheer.  So, are you smiling in your profile picture?
