The world is going crazy

In the world news today, we can see how people in this world have lost their mind..
In Tokyo, somebody modified the DNA of a mouse so that he has no fear of cats.
In Finland, a student shot 8 people in his school and killed himself. He even uploaded video on youtube before he went to kill people. The video was viewed 200 thousands times, but no one was alerted.
In New York, a restaurant is selling a cup of haute chocolate for US$25000. And there ARE people actually buying it.
Back in Tokyo, husbands yell "I love you" on the street to their wives, saying that they are too SHY to say it directly to them.

What are we doing in this world??
Are people really happy living in this world?
Am I the only one who think these are all weird things?
I seriously think that I neve belong to this world.
