A few stiff drinks really does make other people appear more attractive, according to researchers who say the alcohol makes us think about sex.

A test on drunk university students has scientifically proven what was common pub knowledge - that drinking improves the appearance of those around you.

A team from the University of Bristol in England conducted a controlled experiment on 84 young heterosexuals, getting half of them tipsy on a drink and asking all of them to rate the attractiveness of people in photographs.

Both drunk men and drunk women rated the faces as being more attractive than did those who were sober, according to New Scientist magazine.
