Participation in sports at school

Many people claim that doing sports at school is not important  but my view is different. I think it should be as important as other subjects like maths or science because our body  is unique and very important.
Firstly, I think we have only one body and we have to take care of it! One way is to do sports like running to keep fit. Sport is more important when you are groning old to pavement being overweigh. If people have done exercise since they were less than 10 years old they aren't as likely to have health problems.
On the other hand, I think what the schools have to do is encourage students to practice sports and provide information to the parents to make them aware of how important it is.
To sum up, sport is very important to have a healthy body and a healthy life.
