What can humans learn from pigs about optimism?

LOS ANGELES - We know optimists are healthier, happier, and destined to live longer. Optimists are surely delighted by these findings- but what about pessimists? No, they aren’t doomed to be the victims of a self-fulfilling prophecy. Ever the optimists, we believe that being aware of the reasoning behind our feelings means that we have the power to change them.

Psychologists believe our outlook is determined by both our personality (which is constant) and our mood (which is affected by our environment.) If you want to feel more optimistic- look no further than the barnyard.

Watch the video above. If we can see the human tendency towards pessimism playout in the exact same way with livestock- maybe changing our own outlook isn’t as complicated as we thought.
