Five units? That's two pints of 4.4% beer. That's not a binge, that's a pub lunch.
Is that a problem with my attitude toward alcohol, or unrealistic definitions from the studies? I get increasingly skeptical about proposals to crack down on "binge drinking" when the definition is so far from my expectations. I'm all for measures to reduce the frequency and effect of aggressive drunkeness, but not if those implementing them think that having a couple of pints is a problem.
