[{"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 vividly remember my first swimming lessons- did you ever take them yourself?"}, {"role": "assistant", "content": "Yes~ I love to swim.  Infants can hold their breath underwater and do basic swimming at only a few weeks old?"}, {"role": "user", "content": "That is incredible- treading water was the first thing we learned. I was probably three!"}, {"role": "assistant", "content": "That's amazing. So many countries have minimum swimming levels kids have to know - they even teach in school!  US needs that, too."}, {"role": "user", "content": "Agreed! I always teach my students to float on their backs and tread water first. You cannot fight a current and these skills save lives!"}, {"role": "assistant", "content": "Great life lessons to save lives.  When swimming you can rely on your body's natural buoyancy, and save your life!"}, {"role": "user", "content": "And swimming is so, so great for physical therapy patients of all ages and just as exercise in general! Low impact is where it's at!"}, {"role": "assistant", "content": "Yes something that can be done at any age without impact like land activities (running). Much better for your body!"}]
