Swimming is just great. People use it for exercise and sport, and fun, and even survival!
Swimming is really effective exercise because it uses most major body systems.
You ever take swimming lessons? Most countries teach children to swim to a certain level in school
I never took swimming lessons but my 5 year old takes them twice a week. He is a very proficient swimmer which is important since we live in Florida.
Did you ever teach them to swim as a baby? Babies will instinctively move themselves through the water and can actually swim!
