Until the age of 17, he studied in the Siberian village, where in winter -50, and in summer +40.
My Christian also grew up in this village, I remember one of the stories well:
"I hit somehow the frost at 50, naturally did not go to school, but took a solder lamp, heated the motorcycle and went for 30 km to fish. In fact, it had to be rolled back, because the soldering lamp was safely forgotten at home."
