Much has been written about the dangers of drunk driving, but what about drunk walking? Academics Steven Levitt and Stephen Dubner explore the perils of this unspoken killer.

As it turns out, drunk walking is actually eight times more dangerous. Now you might argue that drunk walking doesn’t have the same potential to harm others, but even when that’s factored in we’re still talking about five times as many deaths attributed to drunk walking.

Now don’t get me wrong. No one’s suggesting you should drive drunk rather than shambling home. Instead you may want to call that taxi, or just find a quiet corner and catch some zees until you sober up!
