Task 1. Read the text.

Healthy lifestyle

Today healthy lifestyle is becoming more and more popular both with the old and the young. People say that the greatest wealth is health. And it’s so true. The healthier we are, the better we feel. The better we feel, the longer we live.

Keeping fit and going in for sports is also important for our health. Lack of exercise in our life is a serious problem. In big cities people spend hours sitting in front of computers, TV-sets and other gadgets. We walk less because we use cars and public transport. We should visit fitness clubs, go jogging, walk much, swim, go cycling or roller-skating or just dance. Doctors say that regular physical activity is necessary for our body. We must understand the harm of bad habits for our health. Smoking, drinking or taking drugs mean serious illnesses. Cigarettes kill about 3 million heavy-smokers every year.

Getting enough sleep, from 8 to 10 hours daily, are also great healthy habits. Sleep is the food for our brain and the rest for our muscles.

Healthy people live longer, they are more successful and they enjoy their life.
