Yeah, and you are usually dead to your family twenty years before alcohol finally stops your body.

But that's the point entirely. Showers and going up stairs are everyday activities: Most of us know someone that's been hurt on stairs or in the shower: Shower falls cause lots of injuries every year.

The risks become overlooked because of familiarity and it makes it easier to minimize the risks. It doesn't help that the downsides often aren't immediate: It takes some years to develop disease from it, after all. In general, it takes hours for you to wind up in the hospital or harm someone else - but most of the time, much like showering or walking up the stairs, nothing of note happens.
