They love to teach you in school that if you drink, every beer you have is going to kill off a shit ton of brain cells. That’s actually not true. Light to moderate drinking doesn’t actually cause any damage at all in most cases. Granted if you’re a super alcoholic binge drinker, yeah, that’s going to mess with your brain, and liver, and kidney, when it damages tissue. But even then It’s not going to start killing cells. It would take so much alcohol to actually start killing cells, that you would die of alcohol poisoning way before it came to that.
