Losing temper in sports

Players lose their temper and the match thereby. Its best to teach athletes to consult someone before getting angry especially in tennis. Players seem to feel that umpires are unfair to them. Cricket is the same too. Sometimes umpires are unfair. But if the players can call timeout and check with someone, a lot of unpleasantness can be avoided. But perhaps the unpleasantness is as interesting or even more interesting than the game itself. Such is life.
