If you think日本3月11日的9.0級大地震是日本自己進行的海底核試驗引起的, you may thank Japanese. Because they find the secret of how to live longer than anyone else in the world. The radiation material which released from 海底核試驗 can contaminate fish and Japanese like to eat fish everyday for the past thousands of years. But Japan has the longest life expectancy in the world.
