I had a motorcycle wreck that messed up my ankle prior to learning to golf. Found that I was spraining that ankle often walking my first year. Then was asked to play in a scramble, we rode and I enjoyed the day much more than walking. Golf courses are not flat, all kinds of holes, dips, and stuff to trip on, not to mention hills and dales. I did not start golfing to exercise. Besides it makes the game move along at a better pace, If I owned a course it would be cart only.
