I would like to throw in the possibility, that the ball could accelerate downwards relative to the habitable part.

Yeah you can do that. You would be wrong and people around you would wonder why you switched the subject. But you can do that.

It is not. Saying so, reduces the intrusiveness and carelessness of the american system and absolute insanity of the chinese scoring system.

The SCHUFA is a problematic institution for sure, but saying it’s equivalent to the chinese scoring system just shows that you don’t know what you are talking about.

There is a fine line between valid criticism of gender roles & sexism.

An example of the former would be, “Men are dangerous for women”. Of course not all men are dangerous, but it describes the experience of many women & how they have to navigate the world, to not be assaulted.

This one describes the dynamic of a relationship between individuals & assigns a thought pattern to one of those individuals, based on their gender.

Maybe I missed some nuances here & I would be glad to be enlightened, but this looks like plain sexism.

Well from personal experience I would argue that there are more than 2 points in life where you age dramatically, because never in my live I have been 44 or 60 years old, but still had at least one phase in live, where my body suddenly felt a lot older.
