All of us has got a fovorite kind of sport, it can be volley, swiming, racing ant etc. and I believe that it's  undoubtedly good, because sport help us find ourselves. But many people use sport just for making some adrenalin and they create more and more dangerous kinds of sport and it's wrong I suppose.

First of all, a huge number of adrenalin promotes arterial tension which render negative things on your hurt because slow down functionality of it. And if don't want many problems with you hurt just avoid getting lots of adrenalin.

The second, when you are really often in extrime condition, you beging lose sense of dangerous, and it isn't less important than previous point. And you should think before doing. 

And I know that a lot of my friends have got opposite point of view, they think that if it calls "EXTREME SPORT" it might be extreme, and there is none of this without danger, I agree with them but there is many other way to die)))

And in the end of this essay I just wanna say go in for sport, but do it without risk for anyone lives)

It is more important to do your duty than to follow your dream.

I think all of us without exception have dreams and duties and sometimes we need make a choice between them. This choice is usually hard for us and sometimes we think that it is impossible for us to decide what is better.
I like example of Viola de Lesseps from film “Shakespeare in Love”. I am sure that she’s brave a woman maybe braver than some men, because it is really hard to do your duty than what do you really want. You know I extremely agree with her choice and I suppose that in the first place must be our duties and just then should be our dreams. I know that many people have another opinion. They believe that dreams are most important thing in our life… but I have to object to this opinion, because if all people followed dreams the world would fall in chaos.
Just lets imagine, you're a surgion and you have got a patient who need serious operation. So and in this moment your favorite band gives a concert in your city, and you have to decide what's more important, and it's hard for you because it's your dream to see that show... I now that it's no realistic, but anyway this example shows us all importance of our choise.
In the of this I just want to say that all of can decide what is better for him or for her but we always must think about consequences of us our actions.
