I think someone kind of missed part of the point. The thing about James Bond is he's in an incredibly dangerous line of work and pretty much assumes someone is going to take him out at some point. Given that he can die on a moment's notice and possibly not even know who did it or why, he lives hard, all the cigarettes, fast women, and potent drinks are part of it. He's generally speaking not a guy who thinks in terms of retiring, given that his basic job is "hey go and infiltrate the lair of this psychotic mad scientist billionaire guy who wants to wipe out the world and whom surrounds himself with world class mercenaries and assasins".
The concern I have with analysis from the direction of this article is that it seems like the first step in someone wanting to say "modernize" James Bond by getting rid of all of his defining bad habits to make him a better role model.
I'll also say that this basic attitude does kind of apply to people in high stress or dangerous jobs across the board. It's why things like the hard drinking cop have become stereotypes and worked their way into fiction, why soldiers in foreign war zones are infamous for their excesses (drugs, booze, and whores), and similar things. I'll also say that if you think Rock Stars are bad, nobody can trash a hotel room like a bunch of celebrating firemen. Airline Stewardesses also seem to have a very stressful job, and let's just say that stereotype also seems to exist for a reason. The point being when your always stressed out, or could literally die on your job tomorrow, you aren't thinking in terms of "gee, is drinking this much all the time going to kill me by the time I'm 60?". If you were to hypothetically ask James Bond what he'd be doing when he was 60 he'd probably have no idea because he wouldn't expect to be alive that far into the future, and if he was, it wouldn't matter because the guy probably drinks largely because he literally has people (and we're talking world class killers here) trying to kill him all the time, which probably causes a lot of stress no matter what demeanor he projects.
