Play Golf = Be Wealthy

I came across an interesting study between people who play golf and the amount of wealth they have. I read about this study in "The Millionaire Mind". The relationship is as follows, if you play golf on a regular basis then there is a good chance you are wealthier than the average person. This holds true because:

1. Golf is a rather expensive sport/hobby
2. Many doctors, lawyers, and CEO's golf
3. Golf is used as a way to entertain clients
4. Golfing is a good way to make contacts with wealthy people

I'm not saying that everyone who golfs is wealthy, but if you golf regularly that is a good chance that you are wealthier than most.
