The only clearly positive effect of TV watching is that people feel relaxed while doing it, and many people are willing to exchange that relaxation for the more enjoyable and useful things they might be doing instead. Like the bear that learned to fill his stomach comfortably, they feel satisfied to be entertained without having to exert themselves.
看电视唯一一个显而易见的好处是能让人们放松，而很多人为了这种放松宁愿牺牲更加有趣和有用的选择。就像学会轻松填饱肚子的狗熊一样，不用付出努力就能得到娱乐让人们感到非常满意。
