"The Happiness Effect" Illustrated by: Dave Wheeler for TIME

This was an illustration that was in the British Medical Journal and it is a metaphor for the contagiousness of happiness and is only the latest in a series of similar phenomena Christakis and Fowler have recently studied. This illustration is a great visual explanation for the so called happiness effect. This is when one person smiles or has a good attitude it rubs off on others around them. I do believe that this is true and there are examples of this effect on a daily basis. And this is an excellent illustration to represent it because the idea behind it is obviously there.
