The kidneys, like the liver, are organs that work tirelessly and unnoticed, until something goes wrong. As long as toxic substances remain in the blood, the kidneys will keep working night and day. Even if their function is compromised due to overwork or damage from infection or injury, the kidneys 'owner will remain unaware of this impairment.
腎臟和肝臟相同，都是「鞠躬盡瘁、死而後已」的器官，只要血液中的毒質沒有排淨，它就會日夜趕工、代償，即使已經因過勞、感染受傷而功能不彰，都沒有感覺。
