"You can only drink 30 or 40 glasses of beer a day, no matter how rich you are." -- Adolphus Busch
There must be an order of magnitude error there, possibly an extra zero in the printed number.
The smoking of four tons looks feasible, for sixty years at about 180g/day (enough tobacco for 9 packs of cigarettes, but used in pipes ).
As an occasional pipe smoker, I can tell you that 180g/day is nigh-on impossible. A "bowl" (the unit you put in the pipe at once) is 1g - 1.5g, or roughly the same amount as in a single cigarette. So, that's 120 - 180 bowls per day. With an unfiltered pipe you would incinerate your tongue in a day smoking that much. Longer stems might help, but that is still a shitload of tobacco.
An extra zero seems plausible. 3 to 5 pints of (likely weak) beer daily isn't out of the question.
500,000 quarts of beer, spread evenly over an 80-year drinking career, still amounts to 34 pints per day. However great his appetites, I'm a bit skeptical of that number.
