What’s your bad food habit? Mine is feeling stressed at work, walking to the vending machine near my desk and buying a Snickers. For the short moments that I’m demolishing the sticky composite of caramel, nougat and peanuts, I feel happy. Afterwards, with the tang of sugar still on my tongue, I wonder why I can never stop myself. Despite the certainty that there will be a bitter aftertaste of self-loathing, I never manage to behave differently to produce a different outcome.
