There is something heroic and noble about physical endeavour. Christopher Isherwood (Chris Ish, as I like to call him) knows what I'm talking about:
'... the uncomplicated relaxed happy mood which is nearly always produced by a workout at the gym. It is so good to feel the body's satisfaction and gratitude; no matter how much it may protest, it likes being forced to perform these tasks.' (A Single Man, p. 87)
The warrior civilisations knew it. And I find myself ready to think and live again, after a heroic exertion of this mortal frame.
