Social and environmental correlates of physical activity: people to see and places to go

Golf is a good walk spoiled. (Mark Twain)

Twain’s idea about golf is rubbish, because it’s sociable and in an attractive outdoor environment. (Stuart Biddle)

Twain obviously did not have the benefit of a good golfing companion or teacher who provided the correct motivational environment for him to enjoy both the golf and the walk.
