Page 99 to 101 Paul gives some ideas of what you can do to open your peripheral vision. I found watching TV side on interesting.(That's not in the book).
Probably one of the most useful is when you're walking along notice what is in the shop windows, Cars on the road etc, what looking straight ahead. Tell yourself what you are noticing occasionally glace to verify. It becomes interesting when you start describing a person walking about 3 feet behind you off to one side. You just slow your pace and let them pass to check your accuracy.
