I think swimming seems so relaxing and enjoyable. I'm not good at it though.
i really love swimming in the ocean!
It's funny how locomotion is achieved through the coordinated movements of the limbs.
i've never thought of it this way :) I wonder if swimming burns more calories than running
It is one of the top recreational activities and in some countries lessons are mandatory in school curriculums. 
how cool is that! Do you know in what schools swimming lessons are mandatory?
Not sure. But I think higher levels of body fat and saltier water lower the density of the body and increase bouyancy.
that's interesting! What other cool facts do you know?
only slightly less dense than water, water supports the weight of the body during swimming. As a result, swimming is “low-impact” compared to land activities such as running. The density and viscosity of water also create resistance for objects moving through the water. Swimming strokes use this resistance to create propulsion, but this same resistance also generates drag on the body.
Hydrodynamics is important to stroke technique for swimming faster, and swimmers who want to swim faster or exhaust less try to reduce the drag of the
those other really good guys play the fancy stuff!" Stone then asked Wallis about the importance of this aspect of playing in the current musical climate, with so many drum clinics taking place. Wallis stated, "It's a very precarious subject really...Not for me. It doesn't work for me, 'cause I've never enjoyed that aspect of drumming at all. But, I really marvel in it and I wonder in it and I watch it myself and think, "wow!". I don't
