It is a pleasure to look at a strong, athletic man and slim beautiful lady.
It is known that healthy people live longer and their career is more successful. To look well you must follow some simple rules: don’t smoke and take drugs, don’t drink alcohol, don’t eat too much chips and sweets, eat more vegetables and fruits, sleep well, do exercises.
We have two lessons of physical training once a week. We do exercises, run, jump, play basketball and pioneer ball, ski in winter. I think that we must have more lessons of physical training than we have now. For example American pupils have their PT lessons every day.
I like to play tennis, to ride a bicycle and to swim. But most of all I like roller-skating. I could hardly wait when snow melted, I put on roller-skates and went outdoors. I spent one or two hours every day skating with my friends and we’ve got a lot of fun!
I don’t smoke (nobody smokes in our family). I know that this very bad habit may cause serious problems in your health. I do my morning exercises, try to eat “healthy” food and think that this is really a good way to live.
