Happy is as Happy Does?

Is there an equation for happiness? According to a group of researchers, the answer is yes. They can’t create happiness, but they say they have figured out a way to predict it. “The researchers say their findings do support the theory that if you have low expectations, you can never be disappointed, but they also found that the positive expectations you have for something — like going to your favorite restaurant with a friend — is a large part of what develops your happiness.” So both high and low expectations make perfect sense. This is why I hate math.
