    La Tomatina, Spain

    Tomato juice flows through the streets of Bunol on the last Wednesday of August as the worlds largest tomato fight happens. Festivities begin in the town square where there is a huge pole covered in soap and with a leg of ham at the top. Participants try to climb up the pole to get the ham as watchers throw buckets of water to them. After a gun is fired to signal the beginning of the fight, people catch the tomatoes and throw each other in the streets until the gun sounds again, marking the end of the event.

    It is true that people with better education are usually able to get better jobs.In other words, they have more chances to choose a good job while people with little or no education don't.It seems that the purpose of education is to make people get jobs.But this isn't accepted by all people.

    Some people may think that a person should spend the best years of his life getting education only for a way of living.This was probably one of the earliest reasons of education.In fact, if education is just a way of making a living, people don't need to spend so much time in school.People can get education for a living in a short time.Subjects like History and Geography need not be taught to everyone.Even Language and Mathematics need not be taught in detail, either.Here it is clear that education is much more than teaching a man to get a way of living.

    Education is well-rounded and it is mainly for improving a man.It is not only to teach him to speak, read and write, but also to develop his creative thinking and other abilities.After that, it is to make him a wise man and thankfully enjoy the achievements of human.Education is to make a man lead a better life. Educated people are expected to be able to listen to good music, read good books, watch plays and most of all take an interest in the world.

    I would agree that making a good living is an important reason for education, but certainly not the most important or the main reason.
