Here is a useful bit of information from Daniel Gilbert's book Stumbling on Happiness.
"In July 2004, the City Council of Monza, Italy, too the unusual step of banning goldfish bowls. They reasoned that goldfish should be kept in rectangular aquariums and not in round bowls because "a fish kept in a bowl has a distorted view of reality and suffers because of this.""
What can one say? If you think your view of reality is a bit off, perhaps it is time to change the container in which you live. Who knows what that might do!
