Going to the beach is a good way to spend our holiday. However, if we are not careful enough, or if we do not have enough knowledge, the beach may prove to be a dangerous place. It is a pity that every summer a few people drown at the beach. In some cases, these people are good swimmers. One cause of the tragedy is riptide. If you find yourself in a riptide, don't panic. And by no means should you try against the tide and swim back to shore. You'll tire yourself out and probably drown. Instead, swim parallel to the beach. A riptide is very narrow.
