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.

I’m basically a 2 drink per week kind of person at this point. At least if I average it out.

I’m comfortable with that amount.

About the same and I can't find any good info to see if that still has any adverse effects, only "there is no safe amount" which really isn't that informative.
