Testing in Tübingen goes like this: queue up, listen to a little music, smoke or flirt.

And then chopsticks in the nose.

“But not to the brain,” as the young woman behind me explains.

Like many people in Tübingen, she looks fantastic.

A switchblade is printed on her black dress.

Over it she wears a coat made of millions and millions of tiny black sequins.

Before the test, you get a bracelet with a QR code around your wrist.

The test result is uploaded 20 minutes later and can be read out using the QR code on the smartphone.

And then freedom begins, as if from another time when it was normal not to see any risk in people, but just to see people.
