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 have always been afraid of the water, which explains why I can't swim."}, {"role": "assistant", "content": "Swimming is very tough, but has many uses, recreation, sport, exercise and even survival!"}, {"role": "user", "content": "Thats very true, I've started taking swim lessons because half world has water on it !"}, {"role": "assistant", "content": "You should be okay, human bodies are naturally buoyant, your body should float, so it is simple to learn"}, {"role": "user", "content": "I always sink when I try to float and I hate the water getting in my ears."}, {"role": "assistant", "content": "We are only slightly less dense, it is 0.98 to 1.00, so you certainly can sink a good bit"}, {"role": "user", "content": "See hahaha, but I heard the dead sea is the best place to float because its so salty."}, {"role": "assistant", "content": "That may be true, but the salinity also makes it harsh for animals and plants"}]
