Scientists at Manchester United have written an equation to explain the phenomenon of "Beer Goggles" - where, upon consumption of alcohol, a person suddenly becomes much more attractive.
However, the formula identifies other variables than just amount of alcohol consumed. The drinker's eyesight, room lighting, smokiness and proximity to the other person are all factors represented in the formula.
Read the BBC Article for more information about the formula or test out the phenomenon yourself with a new Beer Machine.
