In parts of Europe, some people think that wearing wet clothes will give you a cold. They say that after you go swimming, you should quickly put on dry clothes.

But now you can find only sand but no trees, no people. What happened? A scientist studied the rings of the dead trees there; He found that the people had to leave because they had cut down all the trees to make fires and buildings.
