Modern people get too impressed by survivalism
It's nothing to do with "extreme manliness" it is to do with accessing deeper knowledge through physicality than you can access through thought.
As proven by recent analysis of the Pyramid hieroglyphics, there was an ancient culture that had their civilization wiped out at the end of the ice age but manged to spread some of their deeper knowledge to fledgling civilizations in Egypt, Britain, and South America.
This knowledge included precise understanding of the size of the Earth, the precision pattern of the stars, the number of fundamental particles (exactly 266) the shapes of the 10th dimensional strings, and much more. Yet they did not have a single microwave or other survival tool, or even destroy all jungle on Earth. This proves that being closer to the harshness of nature, being aware of death by your side, is the only way to access true quantum physics knowledge.
