I recently read an article about how much time the average person spends doing things around the world. The statistics(数据)are changing all the time, of course—and the survey doesn't cover every country so it may not paint a fair picture of some populations, but it was still fascinating.
The survey showed some interesting differences between countries. For example, Mexicans must have fun, because they laugh more than any other population. Germans spend the most time with friends, and surprisingly maybe, Americans play the most sports. Then there are the toe-tapping(欢快的) Russians: the average Russian dance 15 times a month!
When you add up the amount for different activities in an 80- year lifespan (寿命), you get some shocking results. For example, the average person in the developed world will spend about 11 years in front of a computer, phone, or TV screen—much longer than we spend exercising. It's one important reason why we spend about 25% of our whole lives sitting in a chair!
The other main reason is work. A working life for the most people lasts about 116,000 hours (about 13 years), and you may be sitting down all day at a desk or factory machine. That's bad news, since medical studies have shown that sitting down too much is very bad for your health.
Of course, we spend a lot of our lives sleeping, too—about one third of our lives. That might seem like a waste—we could do more with our lives if we didn't sleep. But scientists say that sleep is important to our physical and mental health. And let's face it. If we stayed up all night, we'd probably just spend the extra time checking our phones!
After reading the survey, I thought about all the time I must have wasted over the years just sitting on the sofa. From now on, I've decided that I'm going to watch less TV, spend less time playing video games, and play more sports. Clearly, if I increase my exercise by only 5%, I'll do enough to run around the world twice!
