What do people do to stay healthy in your country?250 words

Scientists have proved that in order to be physically strong and not ill people should lead a healthy life. Leading a healthy live involves eating more fiber-rich food, regular workout, no addiction to alcohol , smoking, and drugs plus also avoiding stressful situations.
Unfortunately, according to the statistics Russian people do not lead a healthy life and as a result mortality rate is very high in Russia. The most harrowing thing that almost 75 per cent of population are addicted to smoking which can cause a fatal disease such as cancer. Moreover, Russian people are inclined to consume a quite big amount of alcohol which also harms their health.
Russian authorities pursue a police to make the nation more aware about being healthy. There are social advertisements which encourage people to stop smoking and avoid drinking spirits. There are also several campaigns to fight with unhealthy habits. For example, shops are forbidden to sell spirits and cigarettes after 10 p.m. A lot of fitness centers and swimming pools are being build nowadays.
Fortunately, the recent poll carried out among adolescents shows that there is a tendency to improve their fitness and to take care about their health. More and more young people are giving up smoking and take up different sports such as skiing, swimming, and visiting fitness centers.
As for me, I think that I am quite health-conscious. I do not smoke and never drink spirits, most of my diet consists of fruits and vegetables. I often brew green tea and try not to be physically active in one word not to be a couch potato.
