An uncle wanted his nephew to quit smoking because smoking is unhealthy. The uncle attempted to convince the nephew to quit, but the nephew would not agree. The uncle then offered to pay the nephew %5,000 if the nephew quit smoking for one year. It was the uncle’s hope that if he could get the nephew to stop smoking for one year, he would not pick up the unhealthy habit again. The nephew agreed and signed a contract to that effect with the uncle. The nephew quit smoking for one year, but after one year restarted smoking. He now asks for the $5,000, but the uncle refuses to pay. The nephew sues the uncle.What is the likely outcome of the case?
