Researchers at Bangor University found a way to value a smile. Some key results of their analysis include:

• Each smile is worth 1/3^rd of a penny, meaning that three smiles will net you one British penny
• However this is only the case if the smiles are genuine. Non-genuine smiles are worth nothing
• Genuine smiles during times of misery are not appreciated
