Right, everyone knows that darts as a sport is a pile of wank BDO/IBF, whatever, and that its semi-recent 'mass' popularity is more down to the tragic appeal of watching two hideously obese men sweat profusely despite doing about as much exercise as i've done typing this, than the enjoyment of some extraordinary sporting prowess, yeah? Good. Well in light of this, i put it to you that darts is the only mainstream 'sport' in which ANYONE* can succeed, given the practice. I mean, you obviously don't need physical attributes, it's accessible and it's cheap - there are literally NO barriers stopping you from going out there and applying yourself for a couple of years and then winning the world title. This has to be unique in competition sport, no?
*obviously discounting people with no arms, and to a lesser extent, eyes.
