In this TED talk, Nicholas Christakis (nowadays professor at Yale) shares his fascinating research on the influence of the people surround us (and the influence of those that surround those that surround us…and so on).
In short: the question of how happy you are, or how much you weigh, if you start or stop smoking, get married or have children, depends to a large degree on those people that you socialize with, and the people those folks interact with – at least statistically speaking.
It’s a whole new perspective on the adage “You are who you know.”
