<human>: I haven't swum in a long time. What do I need to know before I go?
<bot>: Before you swim, it's important to check the water temperature and make sure that it is comfortable for swimming. You should also assess the current of the body of water and plan your route accordingly. Additionally, be sure to wear sunscreen, a bathing suit, and goggles or a face mask if necessary. Lastly, practice breathing correctly while swimming as this will help keep you safe.
