Agreed, although a single shot of moonshine is a equivalent to a little over a pint of beer. You can drink that and be well within alcohol consumption guidelines in US. Even most alcohol-naïve people would only be minimally intoxicated from a single shot of moonshine.
I'm sure drinking has some effect on you, but I'm not sure one non-peer reviewed which by their own papers shows <18 drinks / week shows baseline within the uncertainty band is evidence of any noticeable mental decline. In fact several of the graphs, it shows an increase in matter volume for low non-zero amounts vs zero.
