The magic was spoiled for me some time ago. I was lying in bed with my brain in freewheel, when the announcer announced that it was "7/7/77!!! And that isn't going to happen again for a thousand years!!!"
But from outer space came the realisation that.. neither was 8/7/77! Nor any other date either.
My 'lucky' number was 7, but nothing good happened, except I lived past it.
I have a Hong Kong-made tape measure somewhere with the even numbers in black and the 'unlucky' odd numbers in red.
