　 Most of us lead unhealthy lives; we spend far too much time sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow-moving. There are some aspects(方面)of our unhealthy lives that we cannot avoid. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

　 For those who do not particularly enjoy competitive sports—and it is especially difficult to do so if you are no good at them—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them un such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

　 Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only half way to good health, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on. Yoga, as practiced in the West is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical(諷刺的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—physical effort on the one hand relaxation on the other—which were the natural way of life of our forefathers.

In 2006, a large number of new Internet sites became popular around the world. Some of these are for communication, others for entertainment.

The blog is one form of communication that increased in popularity. Through these personal websites, people can share their lives, ideas and opinions on the Internet. People of all ages have their own blogs. For young people, they are a way to show their writing and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas with other teachers’, as well as experiences and concerns about their work.

YouTube is another Internet site that became more popular last year. This website lets anyone create, share and watch short videos. These include videos of people singing or dancing, or animals doing funny things. Three young men created YouTube almost two years ago as a personal video sharing service. They recently sold it to Google for more than one and a half billion dollars.

Games and entertainment also became a larger part of the Internet last year. One Internet social site is called Second Life. It is an online world in which computer users create a new self and live a different life. They get married, build homes, operate businesses, buy and sell goods, work, play and attend school.
