In junior high, I watched my teacher drop a rat brain into alcohol, and the alcohol seemed to eat away at the brain. So alcohol kills brain cells, right? Well, not exactly. The alcohol that you drink enters your bloodstream, and doesn’t actually attack your brain directly. Of course, there are other ways for alcohol to injure your brain: for example, binge drinking can lead to decrease in breathing and injury to your brain that way.
More things that don’t kill you here.
