I live in SE London and where I live everything is walking distance. I also don't drive, so I am always quite active, plus I usually go the gym twice to three times a week too.

You can exercise in so many situations. If you have walked to the shops and have two heavy bags, while walking back home you can lift them!! **** I am being serious (as long no one is looking as they would think you look a bit of a sap!!)
