I'm not sure it's the amount they drink, but the basic metabolic reality of aging. Everyone starts to feel it in their 30s and 40s. These writers just choose to keep drinking well past when anyone else would have slowed down or quit.

I feel like it's probably their lifestyles were not flexible enough to accommodate that kind of change without losing out on opportunities. The fear of death and stress of that life would make anyone work harder.
