I am curious and research interesting traditions of countries. That's how I learned that there are beer pools in Czech. In fact, this tradition did not bother me among so many strange, evil, and abnormal traditions. Czechs believe that beer is good for the soul and body. It's sure to be good for the soul when you drink beer. But I don't know how good it would be to swim in it. If it is good for the soul and body, we should all do it!
