So, we have a severe chronic alcoholic using spirits rather than beer, drinking over 40 (UK) units (1 cl of alcohol) per day, who miraculously survived to 44, and drove every day to work.
The point about spirits is for alcoholics the liver damage is greater in those that use spirits rather than those who medicate using beer or other lower abv. drinks even if the alcohol volume is the same. Spirits users will on average die sooner.
