I'd rather be matched by flavuh!

I would be matched with a pile of dung :( On the plus side, it couldn't nag me, and it would have no use for a closet full of shoes. I <3 Dung!

What if either him or her fart while they take a sample of your "smell"?

I'm a firm believer in this. My wife and I are very turned on by each other's odor, and think it's a huge reason why we are still so sexually active after eight years.

I think we just got lucky in that department.

See the quote above yours ;)

I remember ages ago watching a Robert Winston programme where he was talking about this.

He collected a bunch of tee-shirts from college girls and sniffed them (seriously - this was genuine science, not perving) to determine which one he preferred.

The theory he was working on was that you could detect at some level inherited disease resistance through smell, and you would be more attracted to people who had immunities you lacked so that your offspring would have as wide a spectrum of immunities as possible.

He then backed it up with various immunity tests and it correlated with his scoring of the various girl-smells he had sniffed so enthusiastically earlier.
