It's defined in the article. Around 4-5 standard drinks a day for Men or 3 for Women. Which is quite a bit of drinking.

That's how the WHO defines problematic drinking. That is not the bar the study uses. The study uses the bar of being hospitalized for alcohol use disorder.

Where 1 "Canadian standard drink" is 1 bottle of beer, 1 glass of wine or 1 shot of liquor.

That shot size is 43ml so 5 shots totals 215ml of 40% spirits. In the UK a single is 25ml so it's equivalent of 8.6 'singles' / 4.3 'doubles'.

Didn't see the unit, sorry.

So, 1 standard drink = 1 bottle of beer = 1 reasonable glass of wine = 2 shots of liquor.

But I can easily see a retired man downing 4-5 beers a day, especially when hanging around a pub or social or country club all day.

Thank you, I went straight to the paper where the definition was a bit more hidden.

That is interesting:
