 So, phase 290, history of coffee, it dates back to 1400s, substantiated evidence of either coffee drinking or knowledge of coffee, of the tree, is from the 14th century, it's in the Sufi monasteries of Yemen, and by the 16th century, it enriched the rest of Middle, of the Middle East, South India, the rest of Europe, and finally, lastly, to, to America, to America, historyextra, historyextra.com, and this was about, it's the official website for BBC history magazine, and BBC world histories magazine, this is like 1200 years ago, in Africa, East Africa, according to the legend, Kali discovered the energizing and invigorating effects of coffee, when he saw his goats getting excited after eating some berries, Kali told, it's the unmistakable, and so was made, the world's first cup Sufi mystic, he seems to, we're good at interpreting things to make sense, even when at the night Sufi mystic named Gotul Akbar Nuruddin al-Shadheeli, the discovery of coffee, he is said to have spotted berry eating birds flying over his village, unusually energetically, tasting some of the jettisoned berries, I don't know what that means, he too, his girlfriend's cousin actually was saying the other day that he has a high sensitivity to caffeine, sensitivity is in body, to process and metabolize caffeine, sensitivity, sensitivity has more to do with the person's unique genetic makeup, as this determines to what degree a given amount of caffeine will affect a person, so the genetic link is that caffeine is using the enzyme CYP1, it is very little of this enzyme, while others produce a large amount, but most people fall right somewhere in the middle, so it's found that according to a study, gbhealthwatch.com, a study called Trait Caffeine Consumption percent of the population, sensitive, so 10%, I must be in the 10% because a couple of beans grind them up, press them down, third genetic link to caffeine sensitivity involves the type of adenosine receptors a person has in his or her brain, those lacking the correct adenosine receptors in the brain, there's a prefix, it's hyperallergenic, hyper means extremely, so it of course isn't relative to the word that it's prefix for, and in this case we're talking about hyper sensitivity to caffeine and saturation, it's an excessiveness of the word app that it's connected to, so the hyper sensitivity would mean that regular sensitivity, there is specially sensitive, choose the majority of people, 200 to 400 milligrams of caffeine, daily won't reactions, these people have no trouble sleeping as long as the caffeine is consumed early in the hypo sensitivity, hypo like hypothermia means, thermia meaning heat, hypo means instead of hyper being more and excessive, hypo is a lack of, so hypothermia would be a lack of heat, or thermia, so hyposensitive people actually don't have much adverse reactions at all, and this is again about 10%, coffee was a beverage, it was the beverage of choice in Persia, Egypt, Syria, by the thousands of Pilgrims, holy city, by each year from all over the Muslim world, so Yemeni merchants, Yemeni took coffee home from Ethiopia, and began to grow it for themselves, Middle East the popularity of coffee soon spread throughout the Balkans which is um, northern Greece, northeast, then it worked its best overseas to, to America, as well as through the Dutch, coffee was drunk in the home as a domestic beverage, but more significantly, it was also drunk, coffee drinking and conversation were complemented by actual life, naturally like anything that's very revolutionary, and of course affects cerebral, there's gonna be conservative, bi-temperament people that naturally don't like to upset tradition, and that's good because you need people to fight for tradition and change to be properly to prove its value before it's just as a long history of prohibition, fear and suspicion, religious, disquiet, and hypocrisy was executed for his troubles by command of the Sultan who rescinded coffee houses, and coffee warehouses were ransacked, and so of course from East Africa and Mecca and Saudi Arabia and the Balkans, it didn't take long for, for coffee to travel west, this devil's drink is so delicious, coffee has been a century, it goes by the steam, it gets adopted culturally as a, a thing to go out and now this very Pascarose who in 1672 also set up a coffee stall in Paris, Pepe's, Pepe's visit to London, to the London coffee house in 1660, and said he and I, Colonel Slingsby, first time that I ever was there, I found much pleasure in it through the diversity of company and discourse, so it's, that's really, that's, that's really cool honestly, you know, it shows that there are cultural transformations, the house was clearly, you know, relatively new, a new thing, and it, this coffee was his newspaper, his internet, in his diaries he refers to the latest news of the conflict with the Dutch, the comet, so he says the comet, it must have been the most
