n.有病；不干净的

Their unhealthiness is their soundness, and is what carries conviction. 病态是他们的基石，使他们变得具有说服力。

Nor is this surprising: a branch may be diseased and all the rest healthy, but unsoundness at the root diffuses unhealthiness through the whole tree. 这没有什么好奇怪的，一根树枝有病，所有其余部分仍可能是健壮的，但树根有病却会使整棵树枯萎。

Human Being was born with "unhealthiness", toughly searching the meanings of life all the time. 人生而"有病"，总是固执地探求着生活的意义。

On the contrary, When collective consciousness makes turbulence, the body and mind will trap in a state of unhealthiness, unhappiness and unpleasure. 相反的，当意识不和谐时，身心就处在不健康、不幸的、不喜悦的状态。

The discernable unhealthiness of this hard-working scholar discloses a prevalent phenomenon that has long existed in China's academia. 这个勤奋学者的不健康状况显示出中国学术界一个长期存在的现象。
