I enjoy swimming

I like swimming as well. It is the self-propulsion of people through water.

What type of swimming skill do you like best

I enjoy doing the butterfly stroke. It is quite a workout.

Of course yes. Do you know some other swimming skill that you can teach me 
1_Wizard
Yeah I know the breastroke, which is when swimmers are on their chest and their torso doesn't rotate.

Okay. It seems to be fun too. I will try it out. DO you know some background history about swimming?

Sure, humans learned to hold their breath underwater a long time ago so they would not drown. It is a very important skill.
