I swim for exercise, and I time myself over a set distance to give myself a goal and encourage myself to work harder. I am pleased when I swim fast, but I would get no sense of achievement from improving my time if the improvement came out of a bottle.
应该鼓励大众参与到体育运动中来。运动不但使人更健康，还使人更快乐。服用药物的最终结果只能是自欺欺人。我以游泳的方式来锻炼。我在设定距离内给自己计时从而鼓励自己通过更多努力达成目标。当我游得快时我很高兴，但如果我的成绩提升的来源是药瓶，那么即使时间缩短也不会给我带来成就感。
