Talking to Strangers: What We Should Know About the People We Don’t Know

by Malcolm Gladwell

But under certain very particular circumstances—especially if you drink a lot of alcohol very quickly—something else happens. Alcohol hits the hippocampus—small, sausage-like regions on each side of the brain that are responsible for forming memories about our lives. At a blood-alcohol level of roughly 0.08—the legal level of intoxication—the hippocampus starts to struggle. When you wake up the morning after a cocktail party and remember meeting someone but cannot for the life of you remember their name or the story they told you, that’s because the two shots of whiskey you drank in quick succession reached your hippocampus. Drink a little more and the gaps get larger—to the point where maybe you remember pieces of the evening but other details can be summoned only with the greatest difficulty.
