My classmate told me an interesting thing. As to a study, doing housework can produce a kind of hormone which would make you happy. That feeling just feel like falling in love the first time.

   And as to a further study, the majorities expressed that they like mopping the floor most. Here is the conclusion, if you do some housework especially mopping frequently, you will tend to have a happy mood.

   Is it interesting? Guys, if you have any spare time and don’t know what to do, why not try to do some housework? It is a win-win thing.
