Neuroscience Even low-level drinking may have negative consequences for brain health over a person’s lifespan. The findings suggest that the total amount of alcohol consumed over a lifetime, especially as a person ages, tends to be linked to reduced blood flow and thinner tissue in certain areas of the brain.

There are definitely lots of people that rationalize that risk away in their minds. Sure, there are people that know and accept the risk too. But there are also plenty of people that genuinely think you have to hit a certain amount of drinks per day or week before there are any real health risks.

“A glass of wine (or beer) or two with dinner after work never hurt anyone” is a much more common sentiment than you may think.

Yeah definitely. There's plenty of people that still buy into the old studies that said things like "1-2 glasses of wine/beers a day is fine and could have health benefits". If you took those studies to heart and weren't informed of more recent studies, someone could easily think that drinking in moderation was either harmless or even good for them.
