Experimental Brain Implant Lets Man With Paralysis Turn His Thoughts Into Words

A man who is unable to move or speak can now generate words and sentences on a computer using only his thoughts.

The ability comes from an experimental implanted device that decodes signals in the man's brain that once controlled his vocal tract, as researchers reported Wednesday in The New England Journal of Medicine.

The man is currently limited to a vocabulary of just 50 words and communicates at a rate of about 15 words per minute, which is much slower than natural speech.

"This tells us that it's possible," says Edward Chang, a neurosurgeon at the University of California, San Francisco. "I think there's a huge runway to make this better over time."

A device that allowed people who can't speak to communicate using brain circuits previously used for speech would be "more natural, and hopefully effortless compared to current assistive devices," says Chethan Pandarinath, an assistant professor in the Department of Biomedical Engineering at Emory University and Georgia Tech.

Why 'Bless Your Heart' Is the Most Savage Insult in the Country

As a Southerner, I'll tell you this: It's the nicest way you'll ever be called an idiot

Bless your heart is not really a compliment. It sounds sweet as pie, and sometimes is said affectionately about pitiable situations, but it’s often acid-tongued because you’re pitiful and did something you shouldn’t’ve but were too dumb to know better, which is why it’s a perfect saying to export from a region that has hung on for dear life to its manners because it has little else to boast about that isn’t problematic, like the food, or the music. Hell, the manners are problematic, too. Some people call it “nice meanness,” but the ability to sound proper while being awful is a central tenet of Southern identity, and you see it best these days in their holdover sick burns.

Yesterday, for instance, Jennifer Garner, who was born in Houston, announced that she is releasing her memoir titled Bless Your Heart.

It was an April Fools’ joke, but the joke is it’s a reference to the fact that when the world learned about Ben Affleck’s giant unfortunate Phoenix back tattoo, which he actually believes is good, Garner said this: “You know what we would say in my hometown about that? ‘Bless his heart.’”

In other words, she is too polite to say she thinks it’s tacky as using a Bedazzler on a cashmere sweater. So she uses a blow-softener. A sour candy dipped in sugar. A “verbal stiletto.” And why not, when ‘bless his heart’ does two jobs in one? It’s a very satisfying way to criticize someone while being able to act like someone who is above doing that sort of thing, because you’re so polite and all. You get to have it both ways: the sick burn sticks to them, and you’re Teflon.

Remember when President Trump dinged former South Carolina Governor Nikki Haley by saying she was an embarrassment to the state?

The people of South Carolina are embarrassed by Nikki Haley!

— Donald J. Trump (@realDonaldTrump) March 1, 2016

And she said:

@realDonaldTrump: Bless your heart

In the South, where politeness reigns among good people, you have to put your judgments somewhere. It’s not polite to speak ill of people if you were raised right. And it’s a way to excuse yourself from being rude, even though you’re being rude. It just doesn’t sound like it.

“Bless her heart, she has no fashion sense at all” is a good example. There are other versions of this: “God love ’em” and “I’ll pray for you,” as is “How nice for you!”

But for some reason, the saying “bless your heart” has caught on elsewhere, and people are fooled by it unawares, because it sounds like someone is giving you the Gesundheit of well wishes.

Like the time Brit James Corden told Ellen DeGeneres and Patrick Wilson, both Southerners, that his favorite Southern phrase he’d heard was “bless your heart.” He once told a Southern woman he was trying to park and couldn’t get in the space, and the woman said, “Oh, darlin’, bless your heart.” And he thought, “That’s the nicest expression you could ever have.”

The two guests, Ellen DeGeneres and Patrick Wilson, both Southerners, had to break it to him that it’s an insult.

“Oh really,” he said, bummed. “What was she saying?”

“‘You poor, stupid person,’” DeGeneres explained. “It’s like that,” she says, referring to the way she condescendingly patted his wrist.

“It gets you out of anything,” Wilson chimed in. “You could say, ‘She’s a horrible person, bless her heart.’”

“I took it as, ‘Oh my god, she wants to bless my heart, this is beautiful,’” Corden said.

“No,” Ellen deadpanned. “She doesn’t.”

For instance, the first time I heard it was from my second-grade teacher. One day I wore shorts to school in the winter with sandals and socks. Which was pitiful, because we were poor, but clearly also stupid, because my mother let me go to school like that, and dressing for the weather is kind of a 101 skill. My teacher covered all these bases with one saccharine phrase. And that’s the whole thing about it: It sounded really sweet! That’s why it’s so devastating.

What it means is that the speaker thinks you’ve gotten yourself into a bad situation, but part or all of the reason is something your fault — either a choice you made, or the fact that you’re dumb. The sympathy is because you probably can’t help it. Or as we say in the South, you come by it honestly. As in, your parents are dumb, too. But the person is a well-mannered polite person, and they are too polite to say it, or they actually like you anyway. Even though you’re stupid. Kind of generous, right?

Why 'Bless Your Heart' Is the Most Savage Insult in the Country

Like when my sister was riding her bike one summer in sixth grade and decided to steer with her feet, breaking both arms and one finger, and had to spend the summer walking around with two arms upright in a cast and a third finger bandaged as if she was flipping everyone one off. That’s a bless her heart situation.

Here’s another one:

Quote:Little Billy: I am 6 years old (only holds up 4 fingers)
Scarlet: Oh honey, bless your heart, but that’s only 4 fingers.
Little Billy tries again: I am 6 years old (this time holds up the same 4 fingers and 4 more on the other hand)
Scarlet: Child….Bless you and your momma’s heart.

Atlantic writer Amanda Mull, also a Southerner, has commented a bit on Twitter about the phrase spreading and people having trouble understand it:

Quote:people outside the south got way too excited to learn "bless your heart" is there some way we can put the toothpaste back in the tube on that
— Amanda Mull (@amandamull) November 28, 2018

Quote:Can someone do, like, a linguistics story about why no one outside the south can figure out what this phrase actually means or is for
— Amanda Mull (@amandamull) April 3, 2019

But the thing is, and here’s the twist: Sometimes it’s sincere.

Quote:This is infuriating! And non -Southerners want to argue with me about this! It could mean “poor thing I’m sorry you up and got so sick with the flu and are gonna miss your sissy’s birthday party. You were so excited about it bless your heart.”
— Esbee (@Esbee92) April 3, 2019

You could say it to someone you genuinely feel for who is in a bad place because they are pitiably weakened and you feel badly for them. Like their dog dies, or the house is destroyed by a tornado. You’d usually know from the tone, which tends to be empathetic or sassy. Some Southern women say they never hear proper Southern women use it negatively at all, only sincerely, and this is probably part of the confusion in its exporting. It means enough things to enough people that if unfamiliar, you won’t know what hit you, and that will be fine, because you don’t even know what we got away with.

“It’s an expression that has a couple of different implications that go with it, a couple different meanings,” Kirk Hazen, a linguistics professor at Western Virginia University and expert on American dialects, tells MEL by phone.

“And it all is related to power,” he says. “The power of who’s talking and who’s listening. I know it’s gotten really popular. In linguistics we call that ‘enregistered.’”

“On the one hand, it can be a sincere form of endearment and concern where you actually feel empathetic for the person,” he says. “But that isn’t the expression everyone likes to talk about. The one everybody likes to talk about is when the speaker in, say, some perhaps condescending or perhaps biting way, notes that the person is in a bad state. And it’s mostly used, at least historically, by women.”

Hazen says women “couldn’t openly criticize someone else, or didn’t think they had the authority, agency, power to do that, but they make a very cutting comment like ‘Bless your heart, how poor and pitiful you must be,’ it comes off as publicly okay, but everyone knows that it’s a criticism. It still comes across as good manners — you’re not swearing or even openly criticizing them, but you’re absolutely cutting into them.”

Sociologist Lisa Wade might categorize this as “weapons of the weak” — what she says women do when they can’t throw their weight around as men do, but need to exert power.

But the phrase is not well understood outside of the South because the meaning as Southerners know it is a kind of insider knowledge that is learned, or an “in-term” that reveals your regional roots (if your accent doesn’t). You typically only know you’re being politely dinged if someone explains it to you. In a way, the strength of the phrase is the way it straddles insult and empathy so well, which makes it wonderfully versatile.

“On one level, people just don’t understand the context of who would be it saying it and who would have the social positioning to say it,” Hazen says. “On the other hand, most people take Southern accents to be either dumb or quaint, which is another way of saying powerless and without any real consequence or authority. And since it’s most often seen as a feature from women, it’s often denigrated or put down that way. So there’s no sense it could be powerful and cutting.”

Hazen is from Detroit. He compares “bless your heart” to the phrase “y’all,” which has also spread out from the South and is loved by lots of people for its folksy charm. While “y’all” is a gender-neutral way of addressing a room (as opposed to “you guys”), Hazen says, the gendered nature of “bless your heart” makes it feel performative for him to use.

“‘Bless your heart’ is so marked,” he says. “It’s a highly gendered idiom. I only hear women using it. It would come off as odd or joking if I used it at a family conversation.”

So if you’re not from the South, and someone says bless your heart to you, it’s really not that hard to figure out what it means. Yes, it could mean anything from “Sorry you were such a dumbass” to “I am really sorry a bunch of terrible shit happened to you” to “You poor idiot” to “I only have criticism for you but I don’t want to say it meanly” to “I just said something very biting but I’m backpedaling at the end so I don’t seem like a bitch.”

But if you’re trying to figure it out, the only thing to ask yourself is this: Did you just do something really stupid or not? If you don’t know, the answer is yes. Which means the ‘bless your heart’ you just got is the bad one. Sorry. I’ll pray for you.

(Quora) Why do the elderly stop cleaning?

Answered by Mary Gordon:

They are less physically capable of cleaning, and senses can be dulled.

I know for my 92 year old grandfather (who lived independently until the end), part of the problem was he genuinely could not see the dirt or smell it. He was doing his best and did not realize things were getting grimy. He also was in no physical condition to get down on hands and knees and scrub a floor or around the base of a toilet, or reach dust bunnies on a top shelf. Things in his house were shabby and worn as well which added to the impression of neglect.

My MIL had dementia and in the early stages she stopped cleaning because she was oblivious, plus couldn’t have figured out a plan to tackle cleaning something. We got her a housekeeper half days, 5 days a week.

Gratitude Is Good: Why It’s Important And How To Cultivate It

Tracy Brower

I write about happiness, work-life fulfillment and the future of work.

For wellbeing, happiness, performance and patience, cultivate gratitude.

The pandemic has made us weary, and while it might be cathartic to make a list of all we’ve lost, all we’re tired of and all we want to leave behind, expressing gratitude is actually a better idea.

Gratitude is a powerful positive force. Far from a fluffy or frivolous concept, it has real impact on physical health, emotional wellbeing, motivation, engagement and belonging.

Here’s why gratitude is good, and how to bring more gratitude into your day.

Patience and Wellbeing

Most of us are impatient with the pandemic, and 2021 has arrived and the pandemic is still here. We were thrilled to usher in the new year, but we’re going to need to wait a bit longer until life is back to something closer to what it was before. The good news is gratitude can reduce impatience. A study published in Psychological Science found when people focused on being thankful, they were more able to demonstrate patience. In addition, a study published in the Review of Communication found gratitude has a positive impact on our mental and emotional states (optimism is an example) as well as physical health. It also predicts behaviors such as helping others and exercising. All of this means gratitude may be just what we need at the moment—while we’re hanging on—or still traipsing toward the light at the end of the tunnel.

Happiness and Satisfaction

Gratitude is also the root of happiness. It tends to focus you on what you have and replace a sense of what you might be lacking. According to some philosophers, you can’t feel both grateful and unhappy, so when your mind focuses on all you are thankful for, you’re more likely to feel joy. In addition, when you are more grateful, you tend to focus on the present—appreciating right now—and this can reduce a sense of yearning or anxiety about the future. In fact, what you’re grateful for today may be something you hoped for yesterday. In addition, by focusing on all you have, you perceive those elements of your life as growing larger. Hence, gratitude tends to give you a feeling of fullness—that what you have is enough—and this is associated with contentment.

Gratitude is also a “gateway emotion” of sorts. Philosophers over the years have suggested it’s the greatest virtue because it leads to so many others. For example, appreciation of someone can grow into love, gratitude for what you have can lead to greater satisfaction and loving your work can lead to improved performance.


Gratitude is also really good for your relationships and the community of which you’re a part. Specifically, gratitude can foster friendships. A study at the University of New South Wales found when people express appreciation, others perceive that they can form a constructive relationship with them, and tend to invest and contribute to connecting. In addition, according to a study by Portland State University, when people received more expressions of gratitude at work, they reported better sleep, fewer headaches, healthier eating and more satisfaction with their jobs. Expressing gratitude tends to spread positive feelings. You feel good about something and your appreciation makes someone else feel good as well, which contributes to an emotional economy—a give and take of feelings which fosters a positive ethos of the entire group.

Expressing gratitude can also create the conditions for awe and flow. These experiences are more likely when you’re lifted out of yourself. In fact, neuroscience research highlighted in The Happiness Hypothesis by Jonathan Haidt finds experiences of awe and flow are associated with reduction in activity in the parts of the brain which are vigilant and self-focused. Being thankful can liberate you from a preoccupation with yourself and focus you more on the bigger picture—which tends to predict positive experiences.

Cultivating Gratitude

So how can you build your gratitude muscle—and become more appreciative? Here are some simple strategies:
  • Begin and end with intention. Start each day by thinking about all you appreciate and expect from the day, and as you turn out the lights at the end of each day also consider all you’re grateful for.
  • Give continuous attention. Throughout each day, find small things about which you can be thankful. Perhaps the line at the coffee place was shorter this morning or your coworker made you smile. Avoid taking things for granted. Make everything count and bring conscious attention to elements which make you glad.
  • Be expansive. Ensure you’re focusing on being grateful not just for things, but for people and conditions. Perhaps you particularly appreciate the headphones which help make your workout more fun, but also pay attention to the person at the club who made you feel welcome or the fact that you have the capability to walk, lift or stretch.
  • Write it downResearch at Kent State University found when you write down elements you’re grateful for, that simple act can foster happiness and wellbeing. This is probably true because it causes you to pause, focus, reflect and reinforce your positive experiences.
  • Express yourself. Gratitude is both an individual and a team sport. When you share what you’re grateful for in a team environment, it holds even more power. Thank a coworker during a team meeting or provide positive feedback to a colleague during a project session. When gratitude is expressed and shared, it helps both you and the group.
Gratitude is good, and it has plenty of positive effects. It may also be what can help get us through the last miles of the pandemic marathon. Staying present, being attentive to others and appreciating all we have—just as we wait for all we want—can help us get to the finish line.
