Too true. Obesity, no doubt following the American model, is set to be the scourge of the NHS in the UK, and the rest of us (while grateful for our continued health) will end up paying. We all have our pet foibles and would no doubt all like to indulge in more food, drink, sex, drugs, gambling, etc etc than is good for us; while most of these will interfere with our jobs, families etc overeating is a relatively easy way of 'opting out' of a responsible lifestyle. Let the airlines take the lead in declaring that this really isn't good enough and that the unilateral umbrella of political correctness will NOt be extended on these occasions.
I notice there is no 9th Beatitude in the New Testament - "Blessed are the fat, for we really love the greedy sods deep down and think they're all cuddly and cute, even though they're a waste of space and drain all our resources needlessly ..."
