Помогите.Нужет рассказ на англ 15 преложений на тему "Мой любимый спорт"

Hello. Today I want to tell you about my favourite sport. My favourite sport is swimming. I started my trainings 6 years ago and can swim very well. I like this sport, because it is very cool to swim, i think. Because when you are relaxing near the sea, it is nice, that you can swim. Or if someone is drowning, you can save his or her life.  Swimming is one of the olympic sports. It is not very easy, because you need many time to learn swimming well and fast. And you need a lot of strength to win the competitions, because it is very tiring to swim a lot. But i think, if you want to learn how to swim well, you should do it. That's all. I hope, you will like swimming and try to learn to swim well.
