I'm not a drinker, but I think we shouldn't be so strict about it. I usually have a drink once every few months or so, and frankly I don't really care about the impact it has on my health. I suspect it's so minuscule as to not matter at all in the scheme of things.

Same with eating deep fried food. Especially if it's a food that's otherwise quite healthy. A bit of hot oil isn't going to be your undoing. Just don't make these things a habit. Enjoy a bit of indulgence, but be honest with yourself: is this once per month thing becoming a once per week thing, or a once every few days thing? Daily? Don't do that. Recognize vice. But don't be so strict that you never allow anything remotely unhealthy. Humans aren't great at abstinence.

Having said that, there's a reason I don't drink more often and it's because it really is terrible for you. I agree, haha. Just, don't pretend you'll never do bad things ever again. Unless you have far more willpower than I do — that's entirely possible.
