Men's perfect lovers come with a waist-to-hip ratio of 0.7

London, Aug 26 (ANI): Math has solved many a complex equations over the years, and now it can also find you the perfect answer to who might be the best lover for you.

Anthropologist Barnaby Dixson studied what the sexes found attractive in a partner across cultures.

Dixson said the same formula for what men favoured in women came up almost every single time- a waist-to-hip ratio of 0.7.

Which means, a waist measurement exactly 70 per cent of the hip circumference is the perfect number.

Dixson said that men didn't take other factors into account when they saw a woman with that waist-to-hip ratio.

"It is likely that perfect 0.7 ratio sends a biological signal to men that the woman is most fertile and most likely to produce a healthy offspring, no matter what size that woman is," the Scotsman quoted Dixson as saying.

"It is all about the distribution of fat which is directly linked to fertility," Dixson added.

Supermodel Kate Moss, actresses Jessica Alba and Marilyn Monroe plus Victoria's Secret Angel Alessandra Ambrosio all possess the perfect 0.7 ratio. (ANI)
