Also, WADA's Ethics Panel alludes to the value of fairness when they state: "Fairness and Justice: Although individuals are fundamentally different and not equal, and the circumstances under which athletes might have to train are not the same (e.g. due to differences in resources), efforts should be made in sport to provide equal opportunity and to facilitate fair competition" [24]. We take it that the following argument -the unfair inequality of opportunity argument -captures the essence of the objection to permitting ND, inter alia, in statements such as those just quoted: P1: Fairness requires that athletes have equal opportunities to win. P2: The use of ND by some athletes creates greater inequality in the opportunities to win. P3: If P1 and P2, then the use of ND by athletes should be banned. 8 C1: Thus, the use of ND by athletes should be banned.Unfortunately, as we will now show, all three premises of this argument are problematic.Starting with P1, we note that, rightly or not, many reject it, because they think that fairness permits some inequalities of opportunity in sports. In the world of sports, we praise and celebrate the individuals who have won in the genetic and social lottery [25,26]. 9 10 Athletes who win, and whom we think should be allowed to win in sport consistently with fairness, often possess superior athletic qualities as the result of random genetic factors, e.g., those determining muscle mass, height, speed, endurance, mental strength, for which the athletes themselves is not responsible. Moreover, becoming a top athlete takes more than winning in the genetic lottery. It also helps to win in the social lottery. It is a fact that the best athletein many sports typically come from rich countries, or from an elite in a poor country. 11 You can be extremely talented and still never get the opportunity to win an Olympic medal if you grow up in a country without access to good training facilities, skilled trainers and resources for participating in international competitions. Some sports-economic studies indicate that in order for a country to achieve one Olympic gold medal at the 2004 Olympics in Athens, the country had to invest around 37 million Australian dollars (measured by the value of an
