请用英语回答～Risky sports are exciting but dangerous.However,there

First of all, I would like to tell you one of my favorite commericials. That is Nike’s “ Just do it!” I would say nothng is really safe in this world. There is always a potential risk or danger in all kinds of sports, even those indoor sports. For example, each year a number of people drown in the peaceful swimming pool rather than in the wavy oceans . Shall people quit swimming just because of some people drown? No way. This is just like there are airplane crashes each year. But people still take the risk of taking the flights.
Life is short. It is the quality of life that matters. In my opinion, the quality of life is doing something one enjoys most. I personally enjoy playing badminton,swimming, and jogging.As long as I enjoy doing all this stuff, I don't care whether I will hurt my back, or sprain my ankle or something more serious.Of course, taking risks does not mean taking no precautions. A smart sports lover knows how to take care of himself or herself. In a word, if you are doing something you really enjoy, then it is worthwhile. As we all know that great love and great achievements involve great risk.

i don't think so.Because it' too dangerous,what's worse,they will lose their lifes

Sure, why not?
Some things are worth a little risk, sometimes even a big risk. And it's always good to try to push yourself to the limit a bit.
