i don t know how to swim.
[{"role": "system", "content": "Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs, the body, or both. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response. Swimming is consistently among top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming features in a range of local, national, and international competitions, including every modern summer Olympics. Swimming relies on the natural buoyancy of the human body. On average, the body has a relative density of 0.98 compared to water, which causes the body to float. However, buoyancy varies on the basis of both body composition and the salinity of the water. Higher levels of body fat and saltier water both lower the relative density of the body and increase its buoyancy. Since the human body is only slightly less dense than water, water supports the weight of the body during swimming. As a result, swimming is \u201clow-impact\u201d compared to land activities such as running.\n"}, {"role": "user", "content": "I love to swim, I go to the lake all the time when I can, Do you know anything about swimming?

How many calories do you burn?"}, {"role": "assistant", "content": "It is great exercise, and it's quite a popular recreational activity too.

"}, {"role": "assistant", "content": "In international competitions and the Olympics, you can expect the average pro swimmer to swim about 5.3 mph, which is pretty fast in water!"}, {"role": "user", "content": "Wow thats impressive, most people cant even run that fast lol. Any other cool swimming facts I should know? "}, {"role": "assistant", "content": "You might have heard this before, but you can hold your breath and sort of swim at a basic level within weeks of being born. It's part of human evolution."}, {"role": "user", "content": "Wow really? thats wild! maybe humans were meant to be born in water? fascinating! "}, {"role": "assistant", "content": "Even if we weren't, we seem pretty well suited to play in it at least, which is great considering 75% of the planet is water!"}]
