Pain is not just a sensation; it's a complex biological response that tells us something is wrong.
疼痛不仅仅是一种感觉;它是一种复杂的生物反应,告诉我们某些地方出了问题。
We don't inherit the earth from our ancestors; we borrow it from our children.
The only way to do great work is to love what you do.
The earth gives us its treasures, but it's our duty to give back more than we take.
