🟢Playful, wondrous public spaces built for community and possibility

For me, public space is political. I work with communities around the world, and as we know, every community has problems. Some of these problems are solved through the ballot box or city hall meetings or community efforts, like bike lanes and potholes and school budgets. But some problems are beyond the reach of these structures, like food deserts, community well-being and the loss of cultural identity. These problems cannot be solved with the existing tool sets. I believe that public space is the most potent place to discuss these issues, because it contains the richest diversity of perspectives. And that's what makes it so powerful. The existing parks, town squares and sidewalks are not enough, though, which is why I'm interested in creating a new type of public space, one that's built by the community and designed specifically for their needs.
I start by listening and by setting up actual outdoor living rooms, complete with couches, tables, chairs, rugs and lamps, as a way of holding meetings to learn about the issues directly from the community. I use this technique to capture the voices and ideas of people that might not have time or feel comfortable in more formal meetings. So why get someone to sit in a love seat in the middle of the street?
In York, Alabama, the residents bear witness to the abandoned houses that cover the town, which are a constant reminder of the white flight that took place after segregation ended, when white homeowners left the area and let their houses fall into disrepair. Teaming up with the people of York, we transformed an iconic, pink-sided, blighted property in the middle of town into a new house, called "Open House." However, this house has a secret. It physically transforms into a 100-seat open-air theater for plays, movies, music or whatever the community would like to experience. And when it folds back up into the shape of a house, the image of the reclaimed pink siding reminds people of the past. After its opening, the mayor saw the potential in Open House and held the next town hall meeting there. The excitement of this unique gathering space brought new energy and gave a fresh viewpoint to collectively discuss the future of the town.
In Cambridge, Massachusetts, to highlight the issues of energy, waste and climate change, we replaced a garbage can in a park with an anaerobic digester to transform dog waste into usable methane gas. Burning this methane lights the park and reduces greenhouse gases. By slightly changing an everyday experience in public space, the Park Spark Project provokes neighbors to have conversations about the natural and built systems around them and their connection to the environment.
In Lyons, Nebraska, residents spoke about the loss of social life as downtown storefronts began to shutter their doors, a result of the slow violence of disinvestment, which has left many rural downtowns empty. To address this loss of human connection, we used an abandoned storefront to turn Main Street into a movie theater. The storefront wall is modified with hydraulics so that the awning and false front fold down over the sidewalk with the push of a button, providing seating for 100. As the community came together to build a storefront theater, an eccentric postman who makes sci-fi movies starring his cat proposed to make a documentary for the debut. And so that summer, we turned downtown into a movie set and the townspeople into actors to create the movie "Decades," a history of Lyons downtown from its founding to the present moment. On opening night, the main street, which is usually empty after dark, filled with people to watch the story of their town, leaving locals to question: How will we write the next chapter of Lyons? Well, the next chapter started with a series of movie screenings, public events and international musicians, as well as a low-budget film community that has blossomed in Lyons, bringing in people from all over the world and a permanent art gallery that has opened next door.
8👍3
My work harnesses the power of the built environment to focus on issues that communities and local governments have failed to address themselves, by creating projects so custom fit that the community naturally makes it their own. When people from all walks of life have a shared experience in these spaces, it can lead to a paradigm shift in how we see our home, our community and the world. For me, public space is political and becomes powerful when it sparks people's imagination to envision a new future. And although every place I've worked is unique, it all boils down to one thing: if people can sit together, they can dream together.
Thank you.

🟢How to make stress your friend?

I have a confession to make. But first, I want you to make a little confession to me. In the past year, I want you to just raise your hand if you've experienced relatively little stress. Anyone?
How about a moderate amount of stress?
Who has experienced a lot of stress? Yeah. Me too.
But that is not my confession. My confession is this: I am a health psychologist, and my mission is to help people be happier and healthier. But I fear that something I've been teaching for the last 10 years is doing more harm than good, and it has to do with stress. For years I've been telling people, stress makes you sick. It increases the risk of everything from the common cold to cardiovascular disease. Basically, I've turned stress into the enemy. But I have changed my mind about stress, and today, I want to change yours.
Let me start with the study that made me rethink my whole approach to stress. This study tracked 30,000 adults in the United States for eight years, and they started by asking people, "How much stress have you experienced in the last year?" They also asked, "Do you believe that stress is harmful for your health?" And then they used public death records to find out who died.
Okay. Some bad news first. People who experienced a lot of stress in the previous year had a 43 percent increased risk of dying. But that was only true for the people who also believed that stress is harmful for your health.
People who experienced a lot of stress but did not view stress as harmful were no more likely to die. In fact, they had the lowest risk of dying of anyone in the study, including people who had relatively little stress.
Now the researchers estimated that over the eight years they were tracking deaths, 182,000 Americans died prematurely, not from stress, but from the belief that stress is bad for you.
That is over 20,000 deaths a year. Now, if that estimate is correct, that would make believing stress is bad for you the 15th largest cause of death in the United States last year, killing more people than skin cancer, HIV/AIDS and homicide.
You can see why this study freaked me out. Here I've been spending so much energy telling people stress is bad for your health.
So this study got me wondering: Can changing how you think about stress make you healthier? And here the science says yes. When you change your mind about stress, you can change your body's response to stress.
Now to explain how this works, I want you all to pretend that you are participants in a study designed to stress you out. It's called the social stress test. You come into the laboratory, and you're told you have to give a five-minute impromptu speech on your personal weaknesses to a panel of expert evaluators sitting right in front of you, and to make sure you feel the pressure, there are bright lights and a camera in your face, kind of like this.
And the evaluators have been trained to give you discouraging, non-verbal feedback, like this.
Now that you're sufficiently demoralized, time for part two: a math test. And unbeknownst to you, the experimenter has been trained to harass you during it. Now we're going to all do this together. It's going to be fun. For me.
Okay.
I want you all to count backwards from 996 in increments of seven. You're going to do this out loud, as fast as you can, starting with 996. Go!
Go faster. Faster please. You're going too slow.
Stop. Stop, stop, stop. That guy made a mistake. We are going to have to start all over again.
You're not very good at this, are you? Okay, so you get the idea. If you were actually in this study, you'd probably be a little stressed out. Your heart might be pounding, you might be breathing faster, maybe breaking out into a sweat. And normally, we interpret these physical changes as anxiety or signs that we aren't coping very well with the pressure.
👍71👏1
But what if you viewed them instead as signs that your body was energized, was preparing you to meet this challenge? Now that is exactly what participants were told in a study conducted at Harvard University. Before they went through the social stress test, they were taught to rethink their stress response as helpful. That pounding heart is preparing you for action. If you're breathing faster, it's no problem. It's getting more oxygen to your brain. And participants who learned to view the stress response as helpful for their performance, well, they were less stressed out, less anxious, more confident, but the most fascinating finding to me was how their physical stress response changed.
Now, in a typical stress response, your heart rate goes up, and your blood vessels constrict like this. And this is one of the reasons that chronic stress is sometimes associated with cardiovascular disease. It's not really healthy to be in this state all the time. But in the study, when participants viewed their stress response as helpful, their blood vessels stayed relaxed like this. Their heart was still pounding, but this is a much healthier cardiovascular profile. It actually looks a lot like what happens in moments of joy and courage. Over a lifetime of stressful experiences, this one biological change could be the difference between a stress-induced heart attack at age 50 and living well into your 90s. And this is really what the new science of stress reveals, that how you think about stress matters.
So my goal as a health psychologist has changed. I no longer want to get rid of your stress. I want to make you better at stress. And we just did a little intervention. If you raised your hand and said you'd had a lot of stress in the last year, we could have saved your life, because hopefully the next time your heart is pounding from stress, you're going to remember this talk and you're going to think to yourself, this is my body helping me rise to this challenge. And when you view stress in that way, your body believes you, and your stress response becomes healthier.
Now I said I have over a decade of demonizing stress to redeem myself from, so we are going to do one more intervention. I want to tell you about one of the most under-appreciated aspects of the stress response, and the idea is this: Stress makes you social.
To understand this side of stress, we need to talk about a hormone, oxytocin, and I know oxytocin has already gotten as much hype as a hormone can get. It even has its own cute nickname, the cuddle hormone, because it's released when you hug someone. But this is a very small part of what oxytocin is involved in.
Oxytocin is a neuro-hormone. It fine-tunes your brain's social instincts. It primes you to do things that strengthen close relationships. Oxytocin makes you crave physical contact with your friends and family. It enhances your empathy. It even makes you more willing to help and support the people you care about. Some people have even suggested we should snort oxytocin... to become more compassionate and caring. But here's what most people don't understand about oxytocin. It's a stress hormone. Your pituitary gland pumps this stuff out as part of the stress response. It's as much a part of your stress response as the adrenaline that makes your heart pound. And when oxytocin is released in the stress response, it is motivating you to seek support. Your biological stress response is nudging you to tell someone how you feel, instead of bottling it up. Your stress response wants to make sure you notice when someone else in your life is struggling so that you can support each other. When life is difficult, your stress response wants you to be surrounded by people who care about you.
Okay, so how is knowing this side of stress going to make you healthier? Well, oxytocin doesn't only act on your brain. It also acts on your body, and one of its main roles in your body is to protect your cardiovascular system from the effects of stress. It's a natural anti-inflammatory. It also helps your blood vessels stay relaxed during stress. But my favorite effect on the body is actually on the heart. Your heart has receptors for this hormone, and oxytocin helps heart cells regenerate and heal from any stress-induced damage. This stress hormone strengthens your heart.
And the cool thing is that all of these physical benefits of oxytocin are enhanced by social contact and social support. So when you reach out to others under stress, either to seek support or to help someone else, you release more of this hormone, your stress response becomes healthier, and you actually recover faster from stress. I find this amazing, that your stress response has a built-in mechanism for stress resilience, and that mechanism is human connection.
I want to finish by telling you about one more study. And listen up, because this study could also save a life. This study tracked about 1,000 adults in the United States, and they ranged in age from 34 to 93, and they started the study by asking, "How much stress have you experienced in the last year?" They also asked, "How much time have you spent helping out friends, neighbors, people in your community?" And then they used public records for the next five years to find out who died.
Okay, so the bad news first: For every major stressful life experience, like financial difficulties or family crisis, that increased the risk of dying by 30 percent. But -- and I hope you are expecting a "but" by now -- but that wasn't true for everyone. People who spent time caring for others showed absolutely no stress-related increase in dying. Zero. Caring created resilience.
And so we see once again that the harmful effects of stress on your health are not inevitable. How you think and how you act can transform your experience of stress. When you choose to view your stress response as helpful, you create the biology of courage. And when you choose to connect with others under stress, you can create resilience. Now I wouldn't necessarily ask for more stressful experiences in my life, but this science has given me a whole new appreciation for stress. Stress gives us access to our hearts. The compassionate heart that finds joy and meaning in connecting with others, and yes, your pounding physical heart, working so hard to give you strength and energy. And when you choose to view stress in this way, you're not just getting better at stress, you're actually making a pretty profound statement. You're saying that you can trust yourself to handle life's challenges. And you're remembering that you don't have to face them alone.
Thank you.
Chris Anderson: This is kind of amazing, what you're telling us. It seems amazing to me that a belief about stress can make so much difference to someone's life expectancy. How would that extend to advice, like, if someone is making a lifestyle choice between, say, a stressful job and a non-stressful job, does it matter which way they go? It's equally wise to go for the stressful job so long as you believe that you can handle it, in some sense?
KM: Yeah, and one thing we know for certain is that chasing meaning is better for your health than trying to avoid discomfort. And so I would say that's really the best way to make decisions, is go after what it is that creates meaning in your life and then trust yourself to handle the stress that follows.
CA: Thank you so much, Kelly. It's pretty cool.

🟢Can exercise actually "boost" your metabolism?

We often hear that exercise can help with weight loss by speeding up or boosting our metabolism. So is it true? Can we use exercise to control our metabolism?
[Body Stuff with Dr. Jen Gunter]
To answer that question, we have to first dig deeper into what metabolism is. No surprise, metabolism is really complex, and scientists and researchers are still discovering many new things about it. Very simply, metabolism is the set of chemical reactions in every cell of our body that harnesses energy to keep us alive.
So much of what happens in our bodies is metabolism, making new cells is metabolism, growing hair is metabolism, and converting food into energy is metabolism. The sum total energy of all the metabolic processes that occur throughout our body is measured in calories. And surprisingly, exercise is usually a small percentage of our daily calorie burn.
Unless you're a professional athlete, most of our calorie expenditure is accounted for by our basal metabolic rate. All the vital stuff we need to function, like having a heartbeat, growing hair, building cells and even blinking. That stuff takes up a big chunk of our energy. So can we hack this equation in some way? Can we use exercise to speed up our metabolism so we burn more energy? Can we burn even more calories? Not just doing burpees, but while we're growing an eyelash, than before?
The answer is no. First of all, this is a misunderstanding of what fast versus slow metabolism really indicates. There's no clear link between thinner people and fast metabolism, and the same goes for larger people and slow metabolism. In fact, if you look at the absolute numbers, people with larger bodies have faster metabolisms, meaning they burn more calories because larger bodies have more cells, which in turn are doing more to sustain the body.
Now, differences in metabolism between people with similar body sizes do exist, but the difference between fast metabolism and slow metabolism can be about 300 calories. That’s like two apples and a banana.
How fast our metabolism works is mostly genetic and related to body size, but there's also age. Our metabolic rate changes a few times over our lifespan. We start with the metabolic rate of an infant. Then there is a switch when we are toddlers, and then it’s pretty stable during adulthood to age 60, when it changes again.
Researchers evaluated the Hadza, a group of people in Tanzania who live a traditional hunter gatherer lifestyle. And yet, when you control for body size and age, they burn a similar amount of calories a day as an average American adult. It seems that calories out is a pretty fixed number, and it appears that our bodies have limits. If we exercise harder, at first we may expend more energy, but over time, our metabolism will find ways to conserve.
Here's what I'm getting at. The point of our metabolic system is to manage energy, not to manage weight. So if you read an article or hear a so-called expert inviting you to boost your metabolism, remember that’s just marketing speak rooted in a weight loss culture. And it just isn’t true.
