My partner is an identical twin. He and his twin brother love many of the same things, but have never been attracted to the same women.

Strange at it may seem, science has an explanation for why this is and, indeed, why we all have a "type" we're attracted to.

When researchers asked 35,000 participants to rate the beauty of different faces, the results were surprising.

We know that certain people are generally accepted as being attractive, but there are plenty of others who we agree to disagree on.

"Although certain characteristics of human faces are broadly considered more attractive (e.g., symmetry, averageness), people also routinely disagree with each other on the relative attractiveness of faces," said the researchers, psychologists from America's Wellesley College.
