Yes, it is actually a geopolitical issue that affects the biology of Americans. The Pacific Province has active volcanoes that expel smoke and when inhaled makes Americans in the region feel lightweight and as if fluctuating. The Columbia Plateau terrain is formes by basaltic lava that erupted millions years ago; this terrain has special characteristics that make it smoother than other types, so Americans feel like fluctuating instead of being in the ground. The Appalachian Highlands were formed by colliding the North America Plate with the African and Eurasian plates, so when American walk through these places they feel like being in a continent other than North America. The list goes on, but we shall also remember America is a capitalist neoliberal country which is a modern framework for society, so Americans are very stressed out by this system that's very different from when they were hunter-gatherers; this difference creates an environment prone to the development of mental illness and believing in conspiracy theories. The result: children shooting schools.
