i enjoy swimming.
[{"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 like to swim although I am not super fast, do you swim at all?"}, {"role": "assistant", "content": "I just learnet that swimming relies on the natural buoyancy of the human body?"}, {"role": "user", "content": "That makes sense, I was always amazed that we can float, I weigh 190 pounds but I still float, that is so odd to me"}, {"role": "assistant", "content": "Yes, I human can learn to swim within weeks of been born"}, {"role": "user", "content": "That is sort of a surprise, babies cannot even walk for a long time after that.
