I drink wine 95% of the time, and never get blackout/fall down drunk.
I haven't done that since adolescence. Not sure why any adult would ever choose to be in such a helpless state.
I suppose it depends on the goal of drinking... if you're drinking to get drunk, yeah, it's probably like you will occasionally go over that line. If you're having a few drinks of something you actually enjoy drinking, and not looking for anything more than a little buzz, you'll never end up in that place.
