There's a radio (and now TV) program called "I've never seen Star Wars" which gets people in the public eye to own up to things they have never done that seem very common to the rest of us.
Its title rang a bell with me because despite being a male engineer who read Sci Fi in his youth - I too have never seen Star Wars.
What everyday things have you never done. Something surprising please. Points will be deducted for superior "I've never got in a fight after drinking 10 pints of Stella" comments.
