According to statistics 20% of teenagers in GB have a disease of some kind. But who is responsible for it.School certainly schould pay more attention teens health. Since children have to sit at a desk all day long they have no time to go out . There are not enough PE lessons at school and as a result children are less active. On the other hand many parents themselves have unhealthy diets. Consequently they are not able to teach their children to eat healthy at home . Parents don not have time to cook healthy food because of a lot of work. and this results in unhealthy eating habits for their children. However I don not think it`s fair to consider parents TV magazines or school responsible for the fact that children ar unhealthy . It`s our own choice as to what we eat and how active we are. WE- children are very lazy nnowadays . If you are unhealthy the person who is responsible for it is yourself.Переведите текст!)))
