No tree gets out of this world alive, and few people come through life without at least one serious illness.

Depression, as medical researchers all the way back to Galen have observed, can set the stage for other illnesses or intensify existing ones.

The moment they have a label to attach to their symptoms, the illness deepens.参考答案：
