people do lot of things to keep healthy. The answer of this statement depends on your own experience and life style. In my point view, keeping healthy is more important than anything else of our lifetime. So, it is easy to judge what the status of healthy in our life is.In my leisure time , i like do several kinds of sports. Among countless factors which influence the choice, these are three obvious aspects as follows.
The first reason for my choice for do sports always is that it is the most favourite thing of me.When I was a child, I do various sports all the time, such as skate, pingpang,bicycle and so on.And I can do these thing verey well, in another word, I'm good at sports. As time's flowing, I have found that sports can make happy, everytime, when my mood was not very well,having some sports can let me lightly as soon as possilble.And this is I will talk about next. In specific aspect, sport is a good psychologist.
This second reason can be seen by every person easily. Every normal person had done sport sor had played games,by the way, just positive games. None of them is lead us to upset.They always funny and happy. So, after some sport, you  will feel not only lightly on your physical,but also brightly on your mental.
Further more, and the mian reason when I have grown, I know that doing sports let me strong and heathy, then I can do something else without worry about if my body could support to.In details,they are good to most of our organs, like lung, heart, vessel, and so on.
On all accounts, heathy is the most important  thing to us, and taking sports can make us more heathy.
