You can survive purely on Guinness
There are many tall tales to come out of the Emerald Isle; leprechauns and pots of gold, that Westlife are credible musicians, that the rhythm method is effective contraception. One of my favourites is that Guinness has just enough nutrients in it, that if you only consumed Ireland’s favourite stout, and nothing else, you could survive. There are currently researchers sitting at bars all over the world testing this theory. The results have so far been scrawled on beer mats and are inconclusive.
Is it true? Is it false? Does it matter?
