If you're 40+5 then you're not overdue.
Normal pregnancy is anywhere between 37 and 42 weeks 
None of the old wives tales (curry, long walks, sex, acupressure, standing on one leg singing the alphabet, pineapples, praying to the moon) work. If they did then no-one would need to accept medical induction of labour. If they did work, then they'd be banned throughout pregnancy, and I've yet to see a pineapple or a lamb bhuna with a warning sticker on it.
Anyone who tries them and claims they work is almost guaranteed to be within that 37-42 week window anyway, and therefore full term and likely to go into labour at that time regardless. The same with a sweep - they only work if you're dilating anyway and are likely to go into labour so if you have one and it works, then it was probably going to happen then anyway, and if you have one and it doesn't then you've had someone rummage around in your fanoir unnecessarily and may as well have not bothered 
And if you think I can't possibly understand and am being very unsympathetic, my DD was finally born after induction at 40+16, and I am currently 40+1 with DC2. I am in the late pregnancy boat with you - it's not something that's a long distant memory :)

It's been my status for the last week or so and the bloody irritating excited messages and calls have stopped - bliss!
