Do you swim competetively? It's such great exercise - easy on the joints while still allowing you to build strength and endurance.
I look at swimming as a hobby to be sure, although some people focus on competing with others. 
What is your favorite stroke? Some of them seem so hard! In the breaststroke, you can be disqualified if you even miss one stroke!
Again, that would be for a competing swimmer, and I am a hobby swimmer. I don't mind back stroke, and floating too.
Right, it just seems so hard to master that one. Backstroke is great because you don't have to worry as much about breathing and timing your breath. Breathing is more relaxed in that one.
It can be yes. And much of my swimming is about feeling the experience, the air, being alive. It helps the hobby be more relaxed.
Swimming is super calming and restorative for the mind in addition to being good exercise for your body.
I get surprised sometimes at how tired I am after a good swim, because you realize how much work it takes to stay afloat.
Right! So many people think that you can just float easily. But being able to float is more determined by relative density. If you don't float naturally, you have to work to stay that way.
Also, the body density, and muscle to fat mass, impacts how you float too, with swimming.
Right. And learning how to float properly could be a life saver in an emergency.
