Walking along on the treadmill I looked around me at the women of various shapes and sizes running on their treadmills. I thought, "why not try it?"
So I did. For all of 9 seconds.
I would need to severely batten down the, er, "hatches" for that sort of thing. And by "hatches" I mean all the wobbly bits. Of which I have many.
Maybe in the distant future.
No time soon.
