Playing a round of golf on any one of the many outstanding courses in Montana benefits the brain and body just as much as any of the other outdoor activities. Walking and swinging a club increases blood flow, improving nerve cell connections in your brain, which in turn improves strategic thinking and hand-eye coordination. You burn around 1000 calories per round, a little less if you are using a cart, a little more if you are walking. Also, focusing on that little white ball both near and far improves vision by working the eye muscles.
