1)Being at the age of 6 I was sure that I'll never drink or smoke. Now I'm 16 and I'm not going to drink it being someone's birthday, a holiday or just a day off. I just don't understand why you can drink? I think this is the worst way of passing free time and I just don't understand teenagers who are ruining their health this way, so do not understand those who sits for hours at the computer, because there's just so much fun! In any case, I always find a good way to relax.
2) There are still problems which I touched on in my essay, but I can't write all! But it's all nonsense, for example, in Africa, children and adults often can't find food. Even water is not enough, people are fighting for life every day!
