Personally, I believe that everyone has to competition during their whole life,so there are many competition between many things. I don’t think there is perfect equalibrium.

 For example, people wear diamond, because they want to look better than other people. They want to show their ability to pay by showing off their diamonds. Let me give you another example. Because Malaria spreads quickly, people sometimes die unless they couldn’t control the speed of spreads Malaria.

 It’s not only human being’s case. What about tigers? Tiger attacks people, because they are afraid of the risk of attack that people might attack them first even the tighers don’t know whether tigers feel fear or not.  I think it is a kind of compatition,too. It is related to confidence.

 Then, who don’t feel any fear or competition? It’s a lion,because it’s a kink of animal, so they don’t have to competitive with other animals! So to speak, guys, be the first, because the weak are the prey of the strong.

p.s. I think it is a ‘story’ by using cause and effect.
