Traditional education taught that human economic development progressed from hunting to stock farming and then to agriculture. However, the only real difference is that stock farming is an economic method of obtaining food by domesticating livestock, while agriculture involves domesticating plants. Therefore, this three-stage development theory is no longer accepted. Instead, the development of human civilization can be seen in the evolution of transportation. To understand the nature of how the world changes, we should observe the development of transportation. The increasing speed of movement is the main evidence that society is changing rapidly. - Joseph’s “just my thoughts”
On the highway, I saw a warning saying “Half of the death accidents were not wearing seat belts”. This means, “Even if you wear a seat belt, half die.” “Safety” is emphasized by saying “50% reduction in mortality when wearing seat belts”. In the former, 'probability' was noted, and in the latter, the effect of 'reduction' was emphasized. - Joseph’s “just my thoughts”
