Only humans are the sole creatures on Earth that cook. The starting point of all cooking is the use of fire. Why do humans use fire? The nutrient absorption rate of raw potatoes is 51%, while boiled potatoes have a rate of 95%. Beef-specific proteins are 4 times more digestible when heated. Good digestion allows for greater energy extraction. Apes chew their food for 6 to 8 hours a day, but humans chew for less than an hour. As a result, the human intestines are only two-thirds shorter than those of apes. In contrast, the human brain is larger. The human brain is the most efficient organ for energy in the body. In fact, species of apes with larger brains have smaller intestines, while those with larger intestines possess smaller brains. This is referred to as the “exchange relationship between the brain and the intestine.” Eating boiled foods indicates cooking. This single factor decisively distinguishes humans. Don’t underestimate the significance of cooking. - Joseph’s “just my thoug...
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
