Ach, you should see me push Multi media trolleys around work, all 22 hectares of it. Really my problem does come down to: I like eating way too much. also last year when I was on a no-carbohydates diet I did loose weight, but it was a miserable way to live. I watch my carbs and eat no bread these days--I don't know why eating more fruit and fresh veg is a struggle, but it is. Habits of middle age, I suspect.
