Swimming is considered a low-impact sport.
I have heard of that! Is it true it's best for your joints?
I would imagine so.  In some countries, lessons are even part of a student's education.
That's so interesting. My school never had a team or any physical education required by swimming, I think that would be a really good idea.
I agree.  As it relies on the natural buoyancy of the body, everyone should be able to do it.
Are there any other benefits of swimming? I know it's great cardio.
It's one of the top recrational activities as well, so people obviously enjoy it regardless of other benefits.
I completely believe it. It's so refreshing and a great summer activity.
And the fact that humans can actually hold their breath and make swimming motions just weeks after birth surely points to the fact that we were made to swim.
