With me, it was my liver that was out of order. […] I had the symptoms, beyond all mistake, the chief among them being "a general disinclination to work of any kind."
What I suffer in that way no tongue can tell. From my earliest infancy I have been a martyr to it. As a boy, the disease hardly ever left me for a day. They did not know, then, that it was my liver. Medical science was in a far less advanced state than now, and they used to put it down to laziness.
