All night long you must sing to me, and the thorn must Pierce your heart, and your life-blood must flow into my veins, and become mine.

整个晚上，你都要对我唱歌，我的刺必须要刺穿你的心脏。你赖以生存的鲜血必须要流进我的血管中，成为我的血。

While the dangling-arm shakeout allows good blood flow into the forearm, it doesn't help the flow of "old blood" out of the forearm, due to the arm's position below your heart.

然而由于手臂的位置低于心脏，所以抖动悬垂的手臂只能让新鲜的血液流进前臂，但是不能促进“陈血”流出前臂。

All night long you must sing to me, and the thorn must Pierce your heart, and your life-blood must flow into me veins, and become mine.

你要为我歌唱整个夜晚，我的刺必须穿透你的心脏，你的生命之血将流入我的叶脉，成为我的血液。
