When You're Smilling

In a recent study , a researcher found that athletes whose team mates were in a good mood were more likely to feel happy themselves. Outward signs of bliss are hard to disguise, so many people subconsciously pick up on the good moods of those around them. For instance, most people interpret a smile on a colleague's face as happiness and adjust their own expression and mood to match. And the more content a team mate felt, the better they played. A bad mood diverts attention from performance, but a good one increases your effort and persistence in getting the job done.
