Jack Dorsey’s First Tweet Sells As NFT For Approx. $3.7 Million

The first tweet that Twitter Inc. Chief Executive Jack Dorsey posted to the microblogging site in 2006 has sold as a nonfungible token for about $2.9 million (A$3.7 million), the latest digital collectible to haul in more than US$1 million amid a flurry of interest from buyers.

The winning bidder, Malaysia-based blockchain company Bridge Oracle CEO Sina Estavi, technically owns a digital certificate of the tweet—“just setting up my twttr,” according to Valuables, an NFT marketplace for buying and selling tweets that ran the auction. NFTs work on the blockchain, similar to cryptocurrencies like bitcoin, and serve as digital certificates of authenticity for everything from art to memes.

Mr Dorsey’s tweet itself will continue to live on Twitter, Valuables said, adding that the digital certificate is signed using cryptography and includes the tweet’s metadata such as when the tweet was posted.

“This is not just a tweet!” Mr Estavi tweeted Monday. “I think years later people will realise the true value of this tweet, like the Mona Lisa painting.”

Mr Estavi couldn’t be immediately reached for comment on Monday. He was also the highest bidder to secure an NFT of a tweet from Tesla Inc. CEO Elon Musk, but Mr Musk ultimately changed his mind.

Cryptocurrency investor Justin Sun, who paid a record US$4.6 million in a 2019 charity auction to have lunch with Warren Buffett, was the second-highest bidder for the NFT of Mr Dorsey’s first tweet.

A wide array of content creators have set their sights on the NFT market after Mike Winkelmann, a self-taught artist who goes by the professional name of Beeple, sold a digital image online at Christie’s for US$69.3 million, making him the third-most-expensive living artist after Jeff Koons and David Hockney.

The overall NFT market ballooned last year to at least US$338 million, from about US$41 million in 2018, according to NFT sales-tracking website NonFungible.com and L’Atelier, a research firm affiliated with BNP Paribas SA.

Mr Dorsey, a bitcoin advocate who also serves as CEO of Square Inc., launched the auction late last year, though bid values crossed the seven-figure mark over the past few weeks. The Twitter co-founder posted tweets showing auction proceeds being converted into bitcoin and sent to the nonprofit group GiveDirectly’s Africa Response project to offer emergency Covid-19 cash relief for families in Kenya, Rwanda, Liberia and Malawi.

Anger Does a Lot More Damage to Your Body Than You Realise

We all get mad now and then. But too much anger can cause problems.

Anger is bad for your health in more ways than you think.

Getting angry doesn’t just hurt our mental health , it’s also damaging to our hearts, brains and gastrointestinal systems, according to doctors and recent research. Of course, it’s a normal emotion that everyone feels—few of us stay serene when a driver cuts us off or a boss makes us stay late. But getting mad too often or for too long can cause problems.

There are ways to keep your anger from doing too much damage. Techniques like meditation can help, as can learning to express your anger in healthier ways.

One recent study looked at anger’s effects on the heart. It found that anger can raise the risk of heart attacks because it impairs the functioning of blood vessels, according to a May study in the Journal of the American Heart Association .

Researchers examined the impact of three different emotions on the heart: anger, anxiety and sadness. One participant group did a task that made them angry, another did a task that made them anxious, while a third did an exercise designed to induce sadness.

The scientists then tested the functioning of the blood vessels in each participant, using a blood pressure cuff to squeeze and release the blood flow in the arm. Those in the angry group had worse blood flow than those in the others; their blood vessels didn’t dilate as much.

“We speculate over time if you’re getting these chronic insults to your arteries because you get angry a lot, that will leave you at risk for having heart disease ,” says Dr. Daichi Shimbo, a professor of medicine at Columbia University and lead author of the study.

Your gastrointestinal system

Doctors are also gaining a better understanding of how anger affects your GI system.

When someone becomes angry, the body produces numerous proteins and hormones that increase inflammation in the body. Chronic inflammation can raise your risk of many diseases.

The body’s sympathetic nervous system—or “fight or flight” system—is also activated, which shunts blood away from the gut to major muscles, says Stephen Lupe, director of behavioural medicine at the Cleveland Clinic’s department of gastroenterology, hepatology and nutrition. This slows down movement in the GI tract, which can lead to problems like constipation.

In addition, the space in between cells in the lining of the intestines opens up, which allows more food and waste to go in those gaps, creating more inflammation that can fuel symptoms such as stomach pain, bloating or constipation.

Your brain

Anger can harm our cognitive functioning, says Joyce Tam, an assistant professor of psychiatry and behavioral sciences at Rush University Medical Center in Chicago. It involves the nerve cells in the prefrontal cortex, the front area of our brain that can affect attention, cognitive control and our ability to regulate emotions.

Anger can trigger the body to release stress hormones into the bloodstream. High levels of stress hormones can damage nerve cells in the brain’s prefrontal cortex and the hippocampus, says Tam.

Damage in the prefrontal cortex can affect decision-making, attention and executive function, she adds.

The hippocampus, meanwhile, is the main part of the brain used in memory. So when neurons are damaged, that can disrupt the ability to learn and retain information, says Tam.

What you can do about it

First, figure out if you’re angry too much or too often. There’s no hard and fast rule. But you may have cause for concern if you’re angry for more days than not, or for large portions of the day, says Antonia Seligowski, an assistant professor of psychiatry at Massachusetts General Hospital and Harvard Medical School, who studies the brain-heart connection.

Getting mad briefly is different than experiencing chronic anger, she says.

“If you have an angry conversation every now and again or you get upset every now and again, that’s within the normal human experience,” she says. “When a negative emotion is prolonged, when you’re really having a lot more of it and maybe more intensely, that’s where it’s bad for your health.”

Try mental-health exercises. Her group is looking at whether mental-health treatments, like certain types of talk therapy or breathing exercises, may also be able to improve some of the physical problems caused by anger.

Other doctors recommend anger-management strategies. Hypnosis, meditation and mindfulness can help, says the Cleveland Clinic’s Lupe. So too can changing the way you respond to anger.

Slow down your reactions. Try to notice how you feel and slow down your response, and then learn to express it. You also want to make sure you’re not suppressing the feeling, as that can backfire and exacerbate the emotion.

Instead of yelling at a family member when you’re angry or slamming something down, say, “I am angry because X, Y and Z, and therefore I don’t feel like eating with you or I need a hug or support,” suggests Lupe.

“Slow the process down,” he says.
