For a very simple example, you punch a hole in your ear lobe, your body will repeatedly try to close the hole, because it says, this is not the way we are meant to be. We are not meant to have holes in that location.
You can force it to accept it by keeping something in the hole until the heals that way but if you ever stop the hole will close up. Not cleanly but it will close.
Your body is not impressed by fashion. It is following a higher law.
You can think you are a male, a female or neither but your body is not interested in what ever delusion you have decided to follow to get dopamine hits from bots. It is going to try to fix the stupid changes you have tried to make.
Excellent explanation, and true!
