Manual Labor

I am not a manual labourer and please God I never shall be one, but there are some kinds of manual work that I could do if I had to.  At a pitch I could be a tolerable road-sweeper or an inefficient gardener or even a tenth rate farm hand.  But by no conceivable amount of effort or training could I become a coal-minter; the work would kill me in a few weeks (Orwell, The Road to Wigan Pier, 32-33).
