Hogwash more like, amirite?
There's an advert on the underground at the moment that says "Listerine users are more likely to talk to a stranger on the tube." I have a couple of issues with this advert: one ethical and one mathematical.
First the ethical. It sounds like they're suggesting that that's a good thing. The guidance on talking to strangers on public transport is pretty clear, particularly if you're a man about to approach a woman: just don't. If she'd wanted to talk to you, she would be by now.
Okay. The mathematical issue is a little more subtle.
