Robert Walking was under intensive care—tubes tapped into his veins, machines measuring his vital functions, nurses giving him injections of the medicines his stomach could no longer digest. The difficulty, so the doctors said, was that he had stopped drinking too abruptly. If he would take one small drink a day for a few weeks, his body might adjust to the absence of alcohol and he might live a few years more. Robert Walking would not let them give him that drink, and so they kept him alive with other stimulants.
