series of new ideas towards health, "S" Plan, the new trend in 2009's healthy project, is made up of several

words with "S" as the initial letter (首字母).

     Sleep better

     Sleeping is very important in our daily life. Good sleep means a good beginning next day. That's why

sleeping is considered as the first step among all "S" steps. To get the aim, you'd better give up bad living

habits like smoking and overdrinking, and do more exercise, such as Yoga and Pilates to relax yourself.

Sometimes, even a small thing, such as a flower can light you up! 

     Smart adds your charms

     It is said that girls are praised beautiful because they are smart and intelligent. As time goes, this concept
