Recently I have avoided watching games, not even at a TV live coverage, still less to the match in person. That's because I know I couldn't control myself. When watching a match, I'll inevitably take sides and be emotionally involved, strongly wishing for the triumph of the side over its opponent. As I often side with the "weaker" in a match, watching it will only spell worry and misery for me.
Not long ago when I accompanied my wife to a super world tennis match my horizons broadened as regards sports competition. It seemed to me that wins and losses were relative and transient. What mattered was the ever-higher level achieved through contest. Victory was a result of all the efforts made by both sides. As one of the audience, I should applaud the energetic performance of both to the neglect of the result. Why should I regard the contest as a life-and-death struggle, the winner as survival and the loser as dead?
