It also goes into the differences between subsistence farmers with high activity and sedentary office workers. I find that having been an office worker vs having been a laborer that the body is very dynamic and responds with training very flexibly. Recently I have done some longer stunts of 8-10 work days without a day off and find that human capabilities, as in military and other emergencies, can be upped through fitness, nutrition, operating at higher efficiencies when forced, much like a top athlete. We see how this affects history, politics. High civilizations become quite sedentary, then decadent, focused on pleasure, consumption, turned inwards. Meanwhile outsiders remain living at primitive subsistence levels, with highly effective physical and mental capacities. Once the high civilizations consumes its resources, loses focus and the outsiders learn basic techniques from them the power switch takes place as in Rome. We see this happening under the Biden administration in a classic manner. Mass immigration of impoverished rural immigrants by a secular, urban based government. Trump's people are more rural, religious, business oriented, active. This switch, along with a drastic reduction in overhead will prolong the American system. If the same occurs in Western Europe remains to be seen. Modern life is based on readily available fossil fuels, i.e. car centered lives with central heating, cooking, office jobs. Poor immigrants from harsh environments could see this as a sort of paradise after scraping the land for sustenance. Human physical energy, activity, ingenuity can be expanded enormously to obtain easy resources, as in gold rush times. Mass immigration in the 19th century to the New World for industry jobs, farmlands is similar to the immigration now to industrial and welfare states from impoverished areas. Human evolution means every individual effort at survival will be made to obtain resources readily available and unprotected on earth. Once word of gold in Alaska, California got out the rush was in. It is now no different.
