數位生活

When it comes to the resource of happniess, most people may answer that possessing what we

are eager is the most important thing whch we feel happy.  And this comment failed because of a survey

which show the relaton between average income and the happy index. Through this survey, 

we will stonish as the most riches country doesn't mean that the people in their country feel happy mentally.

The turlly happiness is not proportional to the salary according to the survey. And if plotting the related dot on the 

paper , the reasearch find that the figure is similar to the  half segment of the production functon which is a curve which 

slope is deeper in the beginning and smooth in the latter .The meaning of the shpae is that the material actually 

satisfies the basic level.  With the increasing salary , the people is used to the material. And the following , new things 

are not longer to stimulate the people.  This can be proven that America is ranking by 17 and Janpan is rank by 66 compare 

to the Bhutan which is ranking by the 8th.  How come?? 

Explaining the phenomenon need much words. And reader can  find the answer by yourself !!
