Swimming is one of my favorite forms of exercise! It's great for recreation too! Do you like to swim?
I love to swim but not like a sport, more like for fun.
You aren't alone! Swimming is consistently ranked among top recreational activities! In some countries, swimming is taught as part of regular educational curriculum!
Great, everyone should learn how to swim if only to be safe around water.  Do you know what age is considered ideal to learn how to swim?
The earlier, the better as humans have a natural love of water. I recently learned that babies can perform rudimentary locomotive swimming within weeks of birth. 
Yes, I guess it is instinctive, animals seem to know how to swim without learning, do you know if they can swim from birth?
I think that's true for many animals! Although we as humans have a bit of an advantage because of the natural buoyancy of our bodies.
And why human body have more natural buoyancy than other animals?
