Last New Year, my flatmate, Fran, and her equally competitive sister challenged each other to go without chocolate for a whole year. I can understand the sibling rivalry/dare thing (I've got a date with my little brother to see who can eat a tub of ice cream the fastest) but chocolate? A whole year? It did not compute. Thankfully they had a clause in their contract* whereby they could eat chocolate if it was covering licorice.
