Human: I haven't swum in a long time. What do I need to know before I go? Assistant: 
Before you swim, it is important to remember that the water can be very cold and can cause shock if you are not prepared. Make sure you wear appropriate clothing such as a bathing suit, goggles, and a cap. Also, make sure you have access to a lifeguard or other trained person who can help you should you become distressed while swimming. Additionally, check your local regulations regarding open water swimming and ensure that you follow them. Lastly, don't forget to bring a towel for drying off afterwards!
