I think nothing is more important then health. Without health, nothing else is worth having. For example a man with a few million ringgit who suffer from incurable cancer. Even with his vast wealth, he is doomed with a painful and early death. So, what is the use of money if one does not have health?Money can only buy you the best health care possible, but that does not guarentee you long life. Infact, people who have less money have healthier lives then those who have lots of money.

There are some arguments for including physical exercise in schools. To begin with, exercise will promote healthy atmosphere in school. Healthy students will be able to study better and can be fully active in class participation. In addition, daily exercise will helps students deal with overweight problem. On the other hand, there are several strong arguments against the idea that students should be exercising in schools.
