Why do we feel pain? 我们为什么会感到疼痛？

Together, we discover that pain isn't the enemy — it's actually your body's alarm system, sending signals through tiny nerve "wires" to your brain in less than a second to say something's wrong. We also learn what happens to people who are born unable to feel pain at all, and why that's far more dangerous than it sounds.

我们会发现，疼痛其实不是坏人——它是身体的警报系统，透过神经这些细细的"电线"，在不到一秒钟的时间里，把信号送到大脑，告诉你哪里出了问题。我们还会认识那些天生感觉不到疼痛的人，了解为什么这其实比听起来危险得多。

Perfect for little listeners aged 5–8.
