One reason I don't swim in lakes..
This is retarded beyond belief. Read this:
Infections by Naegleria fowleri are extremely rare. According to WPIX, only 133 cases have been reported in the U.S. over the past 53 years.
Just because there is a one in quadrillion chance that you might get infected by
Naegleria fowleri, you will avoid swimming in lakes? It is like saying that no one should travel on railways, since there is a one in a billion chance that you might get killed as a result of an accident.
