Yogi, I hope you don't fall on the ice 
Good luck with the MOT. I would think it will pass without a problem as you would probably suspect that something was wrong otherwise.
I think a lot of people would be wary of going in a paternoster fearing that they wouldn't get their timing to get out spot on.
I had thought that CDWM contestants applied to be on - that's what the Channel 4 site says. I've no idea as to where they got my details. My brother was also asked to be a contestant some years ago - he thought that he had been suggested to them by someone he worked with. So it's possible that I was suggested by someone who knows me but not that well as they should realise that I'm not an option. My brother didn't participate either.
