I haven't seen the study, but I could believe it. This isn't really what the article talked about, but I caddied for 6 years as a teenager, and during that time, I developed an ability to read the distance to the pin within 5 yards before I even looked at the yardage. I was this accurate from up to 230 yards out. I'm in my mid-20s now and I play golf maybe once or twice a year. I've found that I have lost all distance perception then, even though my vision is still 20/20.
