翻译以下段落: Consider television. The citizens of most Western countries spend significantly more time watching their screens than interacting with their partners, friends, or children. Smoking, it is said, shrinks the average person’s life expectancy by ten years. But why stop there? Spending thirty-four hours per week watching television (the United States average) will occupy fully 30 percent of your waking hours—twenty- three years of the average person’s conscious lifespan. This sounds intolerably dull, but viewing can become habitual, nibbling away at your life until you believe wholeheartedly that you do not have time for any of the things that might lift your mood: learning, reading, exercising, contributing to your community, seeing friends and family, cooking, or cultivating your interests and hobbies. If you spend eight hours a night in bed, you have 112 waking hours a week. Spend thirty-four of them watching television, and you still have seventy-eight hours left that might inadvertently improve your life satisfaction. If you cannot bear another reality show, an alternative readily presents itself: the Internet. The average American usage is twenty-six hours per week or higher, depending on the study. Most surveys explicitly exclude Internet usage that is a part of paid employment, so the vast majority of those hours are voluntary.
