The skateboard is a great sport. Today I am going to talk about the skateboarding. A lot of people argue that the skateboarding is a dangerous sport. Because it might cause some dangers to ourselves if we don't have enough protection, or we might hurt someone else if we play it on the street in a high speed. For me, the skateboarding is a great sport. Two claims stand out. The first is that the skateboarding trains the balance ability which is really important in our daily life. And another claim is that there is no real limit in the place where the skateboarding is been played. So let's take look at the first claim. The balance ability can keeps us away from a lot of dangers. In 2010, there was a statistic shows that 540, 000 people in the world died from fall. Some of them work in height, but there is also a great portion of them are ordinary people, and died because of the occasional unstable environments, such as slippery floor, loosing carpets and uneven surface. A lot of them are old people. When we are getting old, we loose some part of our balance ability. And if we don't keep training it, we loose it much more rapidly. So it's important to train our balance ability from young age. It's evident that skateboarding is great sport to train this ability. Another evidence is that a scientifique research shows that there is a prominent relation between the body balance and intellectual performance. We can explain this research from a very simple example : when a person is concentrating on his work, he needs to sit still, so it requires considerable body control skills. Another scientifique research shows that a kid with a great body balance is less likely to have some sensory weaknesses, such as, dyslexia, Down syndrome, ADD and ADHD.
