 currents can take a person's life really, really fast. And I always highly recommend people not to swim anywhere that there is a current. But if you do, then you need to be a really strong swimmer and you need to be really confident in what you're doing. But like I said, if you're on a river, you should really have a life jacket on because that life jacket's going to help you. But at the same time, I do also tell kids, life jackets aren't going to always keep you up.
