In a study which unlocks the secrets of attraction, psychologists have explored how evolution has affected what's hot and what's not in the modern mating and dating game.
For many, it will come as little surprise. Women don't necessarily go for physical appearance but, rather, power, wealth and status.
"It's not that looks don't matter to women; they simply matter less than other things - in particular, signals of money and security," psychologist and author Viren Swami found.
The study, contained in his book The Psychology Of Physical Attraction, also found that we're a shallow bunch when it comes to waistlines.
People involved in an accident are far more likely to be rescued if they are of a normal weight than their underweight, or overweight, peers.
And when it comes to attracting men, it's not slimness but the WHR - waist-hip ratio - that is important.
Co-author Adrian Furnham said the lower the WHR the better, with female figures such as those of Scarlett Johansson and Marilyn Monroe the most desirable.
Mr Furnham said society had changed from valuing beauty as rugged Tarzan types to perfectly polished Brad Pitts.
"We've all evolved to find other humans attractive. But the cues for recognising beauty have changed over the years.
"We still look out for things like signs of health; a symmetrical face is attractive because people associate it with healthy people who produce healthy children.
"These days, we judge people first by their body size and then by facial characteristics.''
