How Does Pubic Hair Know To Stop Growing?

[bednobs]

and eyelashes?

[JustNotCricket]

Excellent question.
I have no answer, yet.

I do have a similar question. How do dandelions flower at ground height when they are growing between the concrete blocks that make a grid for cars to drive on?

The soul has never been found. Similarly, where is the brain in a plant?

Am I the only one here that shaves my bits?.............

It doesn't. It just falls out when it can no longer go on.

hi beddie
well you have a few good answers
Hair goes thro various cycles
anagen -catagen-telogen

and so it grows and then falls out

so in starvation the phase is prolonged and so the children's eyelashes look like girafffes - longer growth phase

this is also seen in cancer cycles

Those sound like very specialised bikes, Peter.
