The athlete dividing line for me is anything where a skill set and talent is combined with cardio conditioning and endurance improvement that directly effects the competitive outcome. As an avid golfer, i would not say that applies here, same for golf, bowling, checkers, billiards, high diving ( which I suspect many will disagree with as most are very atleletic, and some gymnastics are not not highly cardio fitness based, so i'm getting on rather thin ice, but a disclaimer, I'm not proficient in any of these, and that is a gross understatement
), and drag racing that lasts under 20 sec.
