We defined YEAAH as a shocking experience or state of being that significantly changes an individual's sense of worth. We chose the name "YEAAH" because it is an experience that is even bigger than the English word "Yeah!" We think we all have more than a few memories in our lives that we will never forget. We are convinced that life will seem more wonderful if we can increase the number of such experiences. And if we can create such experiences all over the world, humanity as a whole will be better off.
