I had no idea about this service about the German post. You can send an SMS to the phone number 22122 and in return you get a code that you can write on the letter and it is valid as a stamp.

After several injuries Brazilian pianist João Carlos Martins lost the ability to move his fingers. Then – after more than two decades of not being able to play – a pair of bionic gloves gave him back his abilities to play the piano.
Different German cities made masks mandatory at different points in time. This study uses a synthetic control methodology and finds that requiring face masks to be worn decreased the growth rate of COVID-19 cases by about 40% in Germany.

The outbreak in Chile is now much worse than those in the worst-hit European countries. And as you can see on the line color, Chile is testing very little. In the last week a case was confirmed per every 3! tests. [Source: ]
