Apparently, deeper toned male voices "float the boat" of women at their most fertile times and it could be down to hormones. According to the research, women "like men with dominant voices as they are thought to indicate long-term health and higher reproductive success". So it's a shame that Barry White's dead really, and James Blunt isn't.
But in good news for James Blunt soundalikes everywhere, "the researchers found that when not fertile, women were more likely to be attracted to a more feminine voice signalling a more caring man, more likely to invest in a long-term relationship".
Phew! So at least if the old Berkshire Blunt does "get lucky" at least he won't be impregnating anyone and spreading his vile MOR seed.
