a) drink was for medicinal purposes only (see the doctor's note) b) cigars enhanced his sense of well being while keeping undesirable company at bay and c) stress kept him focused and engaged in life
The fact that he worked in bed ‘til noon and typically drank the whole time may have been the secret to his longevity. His favorite cigar,if I recall correctly, was Anthony y Cleopatra.
