Speaking of undergrowth, why does downstairs hair feel coarse and wiry–same as facial hair and armpit hair.

说到下层灌木丛，为什么往下长的毛发会感觉粗糙、又粗又硬，比如脸上的胡子和腋毛。

I can hear her armpit hair growing from here.

在这里都可以听到她腋毛疯长的声音。

That's pretty weird. -No, it's not, I can pull out my armpit hair too but it's not gonna feel good.

很奇怪 -不 不奇怪 我也能拔腋毛 但不会这么轻描淡写。

But just like your hormones affect your mood, your armpit hair, and so much more, plant hormones affect a whole range of things throughout plants' lives.

但就像你的荷尔蒙会影响你的情绪、腋毛等等一样，植物荷尔蒙也会影响植物一生中的一系列事情。
