Swimming is ability to not drown.
LOL yes. Drowning is defined as respiratory impairment from being in or under a liquid, which is scary to think about
Swimming can be taught at an early age.
YEah,  On average, the body has a relative density of 0.98 compared to water, which causes the body to float; which is a cool little tid bit of info
Yes if density is less than one, you can float!
Swimming is “low-impact” compared to land activities such as running; so it's  a good exercise for older people
Agree. Elders with arthritis, swimming is best type of excercise for joints.
local, national, and international competitions, including every modern Summer Olympics.
Science.
Swimming relies on the nearly neutral 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 body composition, lung inflation, 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
Drowning
Drowning is defined as respiratory impairment as a result of being in or under a liquid. Drowning typically occurs silently, with only a few people able to wave their hands or call for help. Symptoms following rescue may include breathing problems, vomiting, confusion, or unconsciousness. Occasionally symptoms may not appear until up to six hours afterwards. Drowning may be complicated by low body temperature, aspiration of vomit, or acute respiratory distress syndrome.
Drowning is more common when the weather is warm and among those with frequent
