We know that taking iron when you are not deficient does not improve performance and probably hurts above a certain level. With that in mind, answer these questions:
1. An athlete who is iron-deficient supplements iron to correct the deficiency (without exceeding the normal range) and gets faster. Is he cheating?
2. Pretend for a moment that we are in a world where taking iron improves performance regardless of whether or not the taker is deficient. An athlete who is iron-deficient supplements iron to correct the deficiency (without exceeding the normal range) and gets faster. Is he cheating?
