Fine coffee basics Coffee and pepper

As a patient with long-term sleep deprivation, I need coffee after getting up every day to get me out of sleepwalking. Pour brown coffee powder into the filter paper of a coffee machine, like a soldier ready to go to war with the world, pressing gunpowder into a bullet. Then I would soak, then I would drink, then I would go out to drink and hate work, then I was routinely defeated by the world, then I went home to browse Weibo until late, and then the next morning I was walking dead to make coffee. In fact, in retrospect, I didn't like coffee at first sight. Accepting the bitter aroma was like accepting Sister Furong's aura. To "Oh?" And then to "mm-hmm." The process is a kind of learned love that varies from person to person.

Or maybe it's a process of gradually discovering your predestined love (excluding Sister Furong for the time being): a report in the Public Library of Science Genetics in April 2011 said that people's obsession with coffee is likely to be genetic. Based on genome-wide association analysis (GWAS) of more than 40, 000 samples, the authors found that two genes, CYP1A2 and AHR, may affect behavior, with people with the "high intake" genotype consuming 40 micrograms more caffeine a day than those with the "low intake" genotype-about half a cup of Starbucks lattes.

Well, it's genes again, always genes, which makes some people especially like coffee and Sister Furong, but even I, a genetics coffee maniac, would say, "so what?" This conclusion is as dry as skim milk. Continuing to read the article, the author raised it to the level that "coffee dependence may have the same biological basis as alcohol and tobacco dependence," and I said, "mm-hmm." Well, this actually provides coffee addicts with a cover for claiming to be a genetic victim. You can stay up fair and square at night, drink coffee in the morning and drink bags under your eyes like a sumo wrestler's chest. "this is my gene, there's nothing I can do about it." I think it's better to drink coffee in this case than to post a note on the computer that says "browse Weibo again and cut off your hand". Encourage each other. Fortunately, coffee dependence does not have as great an impact on others as nicotine dependence. Every time I see someone who smokes in a small, airtight public place and sings softly, "poison you a thousand times, you feel like spring." I just want to spill the coffee in my hand. Then said, "drink too much coffee, hands shake."

High doses of coffee inevitably lead to trembling. It was because the sheep who had eaten the beans jumped about and kept the shepherds awake while counting the sheep while clenching their teeth to stay awake. In nature, caffeine does not exist to allow animals to run happily in the forest and grass. in fact, caffeine is toxic to many animals because they do not effectively metabolize high doses of caffeine. Significant effects include dogs, horses, parrots, spiders, etc.-finally, scientists force spiders to eat caffeine and see what kind of web they make passionately. Are they expecting spiders to weave a Grateful Dead profile picture? The effect of caffeine on the nervous system of animals is its self-defense function, did not expect to be human "Oh? Mm-hmm. " The land took advantage of. This is reminiscent of the sad story of chili and capsaicin: chili peppers want birds to help them spread their seeds, because their digestive tract is short, they don't chew, and they fly far, so the seeds don't get destroyed and can spread widely; by contrast, mammals that chew and sometimes regurgitate make chili peppers uncomfortable. So chili peppers adopt a "targeted stop" strategy: capsaicin in chili peppers can activate taste receptors in mammals' mouths to cause hot pain. Chili peppers containing capsaicin are so hot that when eaten by mammals, they think they have turned into spicy rabbit heads and dare not eat them again, while birds' mouths do not contain this receptor, so they can eat chili peppers happily and calmly. So chili and birds win-win, and mammals silently go to the stream to drink water.

…… But humans found chili peppers, so "alas!" "Oh?" "mm-hmm". So in April this year, Australia just developed the hottest chili in history with a spicy unit of 1.4 million Scoville. (ordinary chili peppers are about 10, 000 Scoville, and civilian tear gas is only 2 million hot.)

Now guess how many cups of coffee I drank in order to type these words without four or six words.
