Let me present the essence of Germanness. The "Bonusheft".
It might be worth thousands in savings for dental work if you can prove an entry for a check-up every year for the last ten years (mine goes back to the late classical aera).

But now, it turns out, it's defunct. But gets serviced anyway. "Better keep it. Who knows what'll happen in two years" is my dentist's advice.
