The CONTENTED will inherit the Earth, say researchers (but it's bad new for the glum)

Having a positive attitude could be evolutionarily advantageous, researchers have found. They created a series of algorithms to model how simulated humans coped. It found those who survived were more content, and valued long term happiness more that short terms gains. Cornell researchers created a series of algorithms to model how simulated humans coped. It found those who valued long term happiness more that short terms gains fared best.
