Myself and the current MrsC love going for a walk after a meal, even better when eating out we will pick a metro station the furthest away and walk to it through different routes, its a great way to get exercise, chat and see some parts of Hong Kong we would not normally.
If possible I also try to walk between meetings during the day, although that is dependent on the weather, sometimes its just not viable if you want your shirt not to resemble a gym t-shirt after 5 minutes.
I remember years ago being based in New Jersey for a while (Mt Arlington) and finding that I could not actually walk to my office from the hotel using pavements or pedestrian road crossings even though it was less than a mile away, I had to jay walk and cross over grass verges.
