Hang them all, hang them all, hang them all!
... wait. Was this a big deal? Some names and dates of birth and smoker status? This matters... why? No use for identity theft. No use for an invasion of privacy - if you know anyone on the list you already know roughly how old they are, and smoker status isn't a secret (for any smokers labouring under the misapprehension that we don't know you smoke, I'm afraid the smell betrays you at first introduction).
@wize - a list of names and ages of kids is a 'pedo's goldmine'? WTF? Like the presence of children in a household is a mysterious secret which strangers can't uncover?
Please gentlemen, let's try to keep a sense of perspective here.
There's never a rolling eyes smilie when you need one.
