Hi there, I have recently taken up swimming as a hobby - do you like to swim? 
I love to swim, I like it as a recreation although it can also be a sport, or even survival. I'ts nice for exercise too.
My personal favourite stroke is forward stroke, I find this the best for giving me a complete workout! Which stroke do you like the best? 
I think it's my favorite one too actually. All that matters in swimming is coordinated movements of the whole body and the limbs.
And it's low impact on your joints! I recently damaged my knee running, so I've filled the hole in my exercise plan with swimming! 
Sure! Maybe that's why in some countries swimming lessons are compulsory in the educational system. It's such a useful activity and doesn't damage the body.
Maybe! I had a swimming pool in my school when I was younger, but it wasn't compulsory - I wish that we had been made to learn to swim properly! Have you ever swum in open water? 
I was taught how to swim as a toddler, I think this phenomenon is called Infant swimming. Toddlers and babies do it instinctively. Even though I had assistance of course, I don't even remmeber.
