Gym first thing, and I did a total of two hours.  I've only lost half a pound this week, but my BMI is down considerably.  If I can get down to 161 pounds, I should be able to get into my wedding dress.  Dani has calculated that 3600 aerobic steps equals an hour of aerobic exercise - I'm not quite sure how she worked this out, but that's the daily average I'm aiming for.  Watched the Olympic opening ceremony in Beijing, and as usual with this sort of thing, got v. emotional.  I'm not at all patriotic, but anything which brings the whole world together gives me a kind of glow - not nationalist, but planet-ist.  Earth is the best planet in the galaxy, all the rest are rubbish.
