A few years ago, the city council of Monza, Italy, barred pet owners from keeping goldfish in curved bowls... saying that it is cruel to keep a fish in a bowl with curved sides because, gazing out, the fish would have a distorted view of reality. But how do we know we have the true, undistorted picture of reality?
My score was really bad on this because hearing the Stephen Hawking voice in my head was throwing me off. Meanwhile, this is nuts, people think they can understand what fish both perceive and prefer? You have no idea whether this does anything for the fish, but enjoy cleaning out the hard to clean corners of those containers, people.
