For example, the best way to relieve back and neck pain is often to exercise, while treating underlying contributing factors like obesity. But few people are willing to devote the time and effort that such a therapeutic plan demands; they would prefer an injection, operation, or medication.
比如，减轻背痛和颈痛的最佳办法是经常锻炼，同时解决肥胖等基础性因素。但很少有人愿意花时间和努力满足这一疗法的需求；他们宁可打一针、做一次手术或用止痛药。当不存在立竿见影的方法时，他们就会变得很沮丧，从而进一步妨碍了恢复过程。
