It's not the first song lyrics that I've come up with when I was swimming. There's nothing much to do when swimming, you just move your arms and legs a little, and you breathe in and out, in and out... Very relaxing, indeed! I let my mind wander and sometimes come up with weird ideas. Somehow it seems natural to come up with song lyrics about breathing. After towelling myself I had the chorus:
still breathing
still bouncing around
I know
it ain't what you'd been hoping for
still breathing
still messing about
I know
it ain't the future
you had in mind for me
The rest kind of wrote itself. You'll find it if you look for it ;-)
