Tell you what, those Dart Player's are bloody strong "Like BULL ...."
Tough, mentally strong, like all the other Contact Sports.
Not many sports out there other than Boxing, MMA, Swimmers, Athletics, where you are the main person (not in a team), that has a mental noisey crowd, shouting for you or abuse against you.
Imagine a crowd like that in Snooker, Tennis, Shooting .... Ha.
"I see Darts people ...."
