Do you keep yourself healthy?

Dear [Name], Of course, I do something for my healthy. I walk around my house. My house located in new town at Incheon city and there is a small river beside my house. so it is very freshment to walk along the river. I also ride a bicycle along the river, So I am feeling wind and speed. I am very happy with that. sometimes, I am running along the river. the running is very good for health. I water my body after runninng. 2-3 years ago, I started marathone. I could lose my weight 10kg after one month. my blood data returned normal than before. I want to run around my house everyday. but it\'s very difficult to do, because I was very tired after company. These days, I do hula hoop in the living room. my waist is getting fatter. so I would like to return my young. Today it rained all day. so I could not go out. so I will do the walking machine and bicycle machine in the living room. These machine is good for health. but it is difficult to do long time.
