it is a pity that every summer a few people drown at the beach. In some cases, these people were good swimmers. So how did it happen? Riptide!
Riptide is a strong underwater current. It moves quickly away from shore and out to sea. It appears suddenly and pulls its victim under and far off shore. Therefore, people should make it a rule never to swim too far out from the beach.
If you find yourself in a riptide, don't panic. And by no means should you try to go 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. So just a few strokes in the right direction and you'll be out of danger.
