good health is very important for every person. moreover, there is nothing more important than health. wise people even say: “health is above wealth”, because if you don’t care of your health, you can’t study or work properly.

unfortunately, having perfect health is almost impossible nowadays. due to highly polluted environment people suffer from many diseases.

the best way to stay healthy is to do regular morning exercise, to eat healthy products, to sleep at least 8 hours a day and to quit bad habits. the good thing is that people are becoming more health-conscious. in my opinion, the number of smoking and alcohol drinking people is decreasing in our country. this is happening because people started to understand how dangerous these two bad habits are. obesity is another health problem. people, who eat lots of fattening food and do almost no exercise, are often overweight. a healthy diet involves many fruit and vegetables, seafood and wholegrain products. salt, sugar and fat should be avoided. excessive dieting can be also dangerous. some people refuse to eat meat and become vegetarian. however, doctors say that meat is an excellent source of good nutrition.

to my mind, one of the best ways to stay healthy and fit is to go in for various sports. my favourite sport is swimming. i spend a lot of time in the swimming-pool. i think it revitalizes my body and gives me energy for the whole day. other sports i enjoy are cross-country skiing and figure-skating. to stay healthy, it is also important to spend lots of time in the open air. it is especially useful to go for a walk before going to bed.

following these simple rules regularly is the only way to promote our health.

From ancient times people were afraid of natural disasters. these unpredictable disasters killed thousands of people and destroy dozens of cities. it was called "the punishment of the gods". all of these is about the earthquakes. today we can explain what the earthquake is, why it occurs and even define the earthquake-prone areas. so, why do earthquakes happen? scientists say that the reason is the movement of tectonic plates of the earth, taking place because of the volcanic eruptions or underground explosions.  over the past decade we have seen a number of seismic disasters in japan, china, chile, thailand, mexico and in other countries all over the world. in other words, the strongest earthquakes with the disastrous consequences cannot be controlled by a man, but they can be highly predicted. nowadays there are many ways to reduce the damage to a minimum. we use special materials while constructing buildings or applying special architectural solutions as well as long-term or short-term forecasting of probable earthquakes. to conclude, today the earthquakes are much less threatening than fifty years ago. they are no longer considered as the punishment of the heaven, just like a natural phenomenon like rain or fog.
