Earlier quoted context omitted.
But the poster seems to be doing it based on concern due to health posts on HN not because of hangovers or stupid behaviors. Also many people who drink don’t drink to get drunk so hangovers and stupidity aren’t part of the experience.
This is in context of all the experiences you'll miss out on. If you are drinking so little that you are not getting hangovers (and you are older than say 35), then you are drinking so little you might as well substitute the alcohol for something non-alcoholic and do the same thing, because your experience will largely be the same as that of a sober person either way.
People in here are acting like the only thing enjoyable about alcohol are the effects of binge drinking.
