We took in a number of sights, and one thing we both acknowledged is that if we were to move to the UK we would lose a hell of a lot of weight! You don’t actually have a choice. In SA we are really spoilt because we go to work and get into the car that is parked in the garage, then get out in the basement at your company. It’s then into a lift that takes you to within 50 metres of your desk. You repeat this in the evenings and in total, you have done about 100m of walking, maximum (give or take a few metres depending on how often you smoke and have to wander out onto the balcony for a puff.) With normal SA life you have to make a conscious decision to keep in shape and to do some form of exercise each day. In London, between running for the bus and train (which amazes me as they are so frequent yet people still sprint after them; in fact, trains arrive roughly every 2 minutes on certain lines) keeping in shape is not an option! Add to this the fact that food is so expensive and besides, there is so much to do that you will hardly be eating. So without much effort, you would have shed a significant amount of weight. I actually found that after a week in London I had lost a few centimetres. Stuff that had been tight before was “not as tight” by the time I left (I wouldn’t go as far as to say that it was loose, though.)
