Never change your numbers, and NEVER fuck it off because of a queue.
True story this. Around 1996ish when the Lotto hadn't been going that long, an old school friend of mine's husband decided the queue was too long and fucked off putting his numbers on. You can guess what happened and whilst it might sound made up, it isn't. Their numbers came up every single one of them. They ended up getting divorced.
I do the Lotto on line and top up my account each month. Once or twice i've forgotten to do it and have missed a draw or two. I always toy with myself as to whether I should not look at those missed draws incase the numbers had come up, which would render me suicidal. The flip side of that though is if I don't check but they have come up, the likelihood of them ever coming up again is absolutely dead as fuck, so I have to check.
