I go to my chain-smoking chemist to pick up some paracetamol and find that he's stopped puffing. I ask him if he chewed some of his own nicotine gum as an aid. He's offended. 'No, nothing. Only willpower,' he says, handing me my Dolo. I go to the park for a morning walk and people are walking backwards. The same folks go home and drink strange vegetable juices that have no describable taste. Like the hit smoothie called 'The Karela Story'. This, too, is an exercise in willpower.
