Nowadays a growing number of people, especially the 20s or 30s, tend to stay indoors for most of their spare time, especially on holidays, some spend the majority of the time online chatting blogging, shopping, dating or playing computer games. some sit with their eyes glued to the television screen, day and night.
People s opinions vary when it comes to this way of killing time. a great number of people maintain that staying indoors is cheap, comfortable, and most importantly, very safe. Others, however, frown upon staying indoors for too long. they are worried that lack of physical exercise and face-to-face communication with others will do harm to people s body and mind.
Personally, I don t think staying indoors for most of the day should be advocated .Instead, people in all ages, their physical conditions permitting, should be encouraged to more time outdoors .The brilliant sunshine, the pleasant green space, the interactions with other people, etc .are all good for people s health, both physically and psychologically.
