臺灣籍旅美老師今天交給我們的句子是：

Complete rest will also cause your endurance to decrease, leading to fatigue and even more inactivity. And your muscles will begin to atrophy too, losing their mass. And your bones also lose their mass, eventually stabilizing around 40 to 70% of their original mass.
完全不動還將導致你的肌耐力減弱，使得你容易疲累，而且甚至更不想動。而你的肌肉也會開始萎縮，肌肉質也跟著流失。還有，你的骨質也會流失，流失到最后會停留在大約只有原來骨質的40％到70％。
