"The only thing we can try to do is to influence the direction scientists are taking. Since we might soon be able to engineer our desires too, perhap… - Yuval Noah Harari

the better we understand history, the faster history alters its course, and the faster our knowledge becomes outdated.

Consistency is the playground of dull minds.

Farmers tend to eat a very limited and unbalanced diet. Especially in premodern times, most of the calories feeding an agricultural population came from a single crop – such as wheat, potatoes or rice – that lacks some of the vitamins, minerals and other nutritional materials humans need. The typical peasant in traditional China ate rice for breakfast, rice for lunch, and rice for dinner. If she were lucky, she could expect to eat the same on the following day. By contrast, ancient foragers regularly ate dozens of different foodstuffs. The peasant’s ancient ancestor, the forager, may have eaten berries and mushrooms for breakfast; fruits, snails and turtle for lunch; and rabbit steak with wild onions for dinner. Tomorrow’s menu might have been completely different. This variety ensured that the ancient foragers received all the necessary nutrients.
