Actually, this is a completely incorrect statement in the article. If you follow the link they show in the article, it brings you to an article about a survey that TravelZoo did and the question is: "Have you ever taken a tinkle in the ocean or a pool?" The OCEAN or the pool. This completely changes the question and so the 58% regarding 'peeing in a pool' is wrong (it could easily be that 99% of those people peed in the ocean and not a pool, which is very different). Plus it shows that 64% of Americans said "yes" to that question, so the American number is higher. This is what happens when articles just haphazardly brush over actual statistics and completely distort their meaning...
