Once I walk around this Hafen with one of my friends, we discussed a book (*) we both read recently. The discussion goes far and in many directions. But I found two points were interesting. Berlin Westhafen One is as in the title, ``You have no responsibility for what was happened, but you have responsibility for that not happens again.

Japanese data is way less compare to other countries. Figure 1 Data source: minutephysics: How To Tell If We're Beating COVID-19 You might think, a small new case ratio sounds good.
