瞌睡虫

I think if permits, most of us especially the young people would like to be a indoorsman or indoorswoman. I find a strange phenomenon around us. We have lots of forms of entertainment nowadays. For example:  various kinds of ball games, walking, running, dancing, traveling, computing, watching TV and so on. I find most of the old people will choose the outdoor activities like ball sports, running, dancing, etc, and most of the young people will choose indoor activities. So they are called indoorsman or indoorswoman. Undoubtedly, to be indooorsman or indoorswoman is bad to our health. Beware of our health, do not to be a indooorsman or indoorswoman
