New documentary celebrates the beautiful kinship between the Dalai Lama and Desmond Tutu

The friendship between these two "mischievous" spiritual icons is enough to bring hope and joy to any heart.

Dalai Lama, Desmond Tutu, joy
Mission: JOY

The Dalai Lama and Archbishop Desmond Tutu formed a close bond of friendship around shared joy and compassion.

When Archbishop Desmond Tutu passed away, I wrote a bit about the unique friendship he shared with the Dalai Lama. Though they came from very different worlds—different nationalities, different faiths, different backgrounds—they shared a kinship based on compassion and joy.

And when I saw them together in "Mission: JOY"—a documentary on five days the two leaders spent together—I saw how beautiful that kinship truly was.

"Mission: JOY" is as much a reminder of what connects us as human beings as it is a celebration of these two iconic spiritual leaders. I laughed at how they teased one another like schoolboys. (It's also just impossible not to laugh along with Desmond Tutu's infectious laughter.) I teared up as they described how they responded to their own sufferings and showed so much care for one another. I smiled each time one of them lovingly reached out to take the other's hand as they shared stories, wisdom and jokes together.


But mostly, I walked away with a sense of calm hope for what is possible. If a Christian theologian from South Africa and a Buddhist monk from Tibet can form a strong bond of friendship like this with one another, then anyone can. This is a film the whole world needs to see. I think it's safe to say that every person would take something valuable away from it.

Filmmaker Peggy Callahan shared some of the extraordinary experience of making "Mission: JOY" with Upworthy. Our Q&A with her provides some personal insight into the film and what it felt like to spend five days with two of the most influential spiritual leaders of our time.

How and why did you get involved in making this film?

"It was Thanksgiving Day almost seven years ago when I got a call from my 'brother from another mother,' Doug Abrams. He said, 'Do you want to come to Dharamsala and film a conversation between His Holiness the Dalai Lama and Archbishop Desmond Tutu?'

"Of course, there is only one answer to a once-in-a-lifetime invitation like that. And that is how I got to spend five days with two of the people on the planet that I admired most.

"His Holiness the Dalai Lama and Archbishop Desmond Tutu shared deeply about how they managed to create joy for themselves, even during their darkest days. Doug and the two holy men used the transcripts from that days-long conversation to co-author 'The Book of Joy,' which became an international bestseller. And the footage from that conversation was the basis for our film, 'Mission: JOY - Finding Happiness in Troubled Times.'

"It seems to me that documentaries—and most meaningful things in life—require an unreasonable love. The kind of love that propels you. Compels you. Sustains and inspires you to get off the ground and keep going. It’s been a seven-year journey to create this film with a great team of artists. But I suspect the film recreated us all in some way. Unreasonable. Beautiful."

Why was it important to you personally that you create this film?

"I grew up in South Carolina at a time when racism was even thicker than the humidity. My mom is from Canada and didn’t buy into it one bit. You can imagine the salty words she’d whisper in my ear about systemic racism, as if systemic and racism were four-letter words.

"I remember parents of my white friends not allowing their kids to play at my house because my African American friends were there. The prejudice was so stark and so ugly that it never made sense on a primal level, leaving me out of step with the world I walked in. I think there is value in feeling like an outsider who sees the world differently. It’s easier to question. Examine. Appreciate or not. It’s perfect for a journalist or storyteller. Fighting injustice can be a great motivator in your career, and tricky in your personal life.

"Archbishop Tutu and His Holiness, along with people like Nelson Mandela, Martin Luther King Jr. and Mary Robinson were beacons for me because not only did they get up and do something about injustice, their actions were effective at changing power relationships. Their actions made a measurable difference in the daily lives of people who most of the world had forgotten.

"Also, many years ago Archbishop Tutu joined the International Advisory Board of an anti-slavery organization I co-founded called Voices4Freedom, so we had that personal connection as well. It’s the honor of a lifetime to help share Arch’s and His Holiness’s messages with the world, especially now when so many are hurting so much."

What words would you use to describe the relationship between these two global icons?

"These two are FUN, as is obvious within just the first few minutes of the film. They joke and tease each other with abandon. Having lunch with them in the Dalai Lama’s compound was an absolute riot. It had the feeling of getting together with your long-time friends where you knew going in that your stomach was going to hurt from laughing so hard.

"And they are congruent within themselves. There are lots of impressive, powerful leaders in the world that garner respect. Admiration, even. But few of those are so beloved. Why?

"I think it’s because with these two, what is real for them on the inside is what we see on the outside. They lived/live out their values in ways big and small every day, in every interaction, with everyone they encounter. What you see is what is actually real within them. It’s utterly compelling. As evidenced by the fact that, even though they are/were leaders of their respective faith traditions, people from ALL faith traditions and no faith tradition are inspired by them."

Mission: JOY

What were some things that surprised you as you were making this film?

"Can you believe that we had not one technical glitch during the filming in Dharamsala? We had the team members from four countries and needed to truck in equipment from Delhi, which is 12 hours away. If any equipment broke we had no way to get replacements in fast enough. But not one thing went wrong. Which is all the proof I need that holy men were in the house.

"Another surprise was that despite the complications of COVID, we were able to complete the film on time and within budget. Hollywood has technical terms for such occurrences: A miracle. Once in a blue moon. When pigs fly. You get the picture. That’s a huge tribute to the phenomenal team that came together to make this film, including four Academy Award winners."

Why do you think this story is important right now?

"Wouldn’t it be wonderful if no one was hurting and a film like this wasn’t needed? And everyone on the planet already knew about the latest neuroscience and psychology research-based actions to help ourselves feel better? That, incidentally, look astonishingly like what spiritual traditions have been telling us for millennia?

"Even before the pandemic, there was a dramatic uptick in anxiety and depression, especially among young people. Now, one in four people report they are experiencing anxiety and depression. We see this even in our own families and circles of friends, right? People are hurting.

"That’s why we took the messages of the film one step further and operationalized what the Dalai Lama and Archbishop Tutu shared. We partnered with researchers at UC Berkeley’s Greater Good In Action, UC San Francisco, Harvard and a consortium of other universities to create The BIG JOY Project. Anyone can sign up for free, and spend seven minutes a day for seven days trying out a different micro action that science shows boosts moods. At the end of seven days, you’ll get a cool BIG JOY Report that will show you which micro-act of joy works best for you!

"Already people from 108 countries have participated and have completed 38,572 micro-acts of joy! The BIG JOY Project is now the largest ever citizen-science project on joy. You’ve got to see the map of these people from all over the world. It’s a tidal wave of joy! We get excited about each and every additional dot on the map that appears, because we know that means that one more person is getting the quick start owner’s manual of how to be human and create more joy for themselves!"

If there were one lesson you hope people will take from this film, what would it be?

"Arch and His Holiness wanted everyone to know that, no matter their circumstances and no matter how broken they may feel, they are worthy of joy, and they are capable of creating it for themselves. If after seeing the film, people walk away with only that message, we have done our job.

"Archbishop Tutu and His Holiness joined forces one last time before the Archbishop passed away for a final shared mission: to help us create more joy for ourselves. They saw joy as that critical. To me, joy is the ultimate ‘clean fuel’ that powers everything we want to do in life. These great teachers put their hard-earned wisdom about the how-to of joy into movie form, as their final gift to each of us. It is yours to enjoy."

The Dalai Lama's team has organized a global watch event for the film via Facebook on June 2. You can learn more about the film and how to host a screening at missionjoy.org

quiet, finger over lips, don't talk, keep it to yourself, silence

A woman with her finger over her mouth.

It can be hard to stay quiet when you feel like you just have to speak your mind. But sometimes it's not a great idea to share your opinions on current events with your dad or tell your boss where they're wrong in a meeting. And having a bit of self-control during a fight with your spouse is a good way to avoid apologizing the next morning.

Further, when we fight the urge to talk when it's not necessary, we become better listeners and give others a moment in the spotlight to share their views. Building that small mental muscle to respond to events rather than react can make all the difference in social situations.

What is the WAIT method?

One way people have honed the skill of holding back when they feel the burning urge to speak up is the WAIT method, an acronym for the question you should ask yourself in that moment: "Why Am I Talking?" Pausing to consider the question before you open your mouth can shift your focus from "being heard" to "adding value" to any conversation.

The Center for The Empowerment Dynamic has some questions we should consider after taking a WAIT moment:

  • What is my intention behind what I am about to say?
  • What question can I ask to better understand what the other person is saying?
  • Is my need to talk an attempt to divert the attention to me?
  • How might I become comfortable with silence rather than succumb to my urge to talk?

The WAIT method is a good way to avoid talking too much. In work meetings, people who overtalk risk losing everyone's attention and diluting their point to the extent that others aren't quite sure what they were trying to say. Even worse, they can come across as attention hogs or know-it-alls. Often, the people who get to the heart of the matter succinctly are the ones who are noticed and respected.

Just because you're commanding the attention of the room doesn't mean you're doing yourself any favors or helping other people in the conversation.

The WAIT method is also a great way to give yourself a breather and let things sit for a moment during a heated, emotional discussion. It gives you a chance to cool down and rethink your goals for the conversation. It can also help you avoid saying something you regret.

How much should I talk in a meeting?

So if it's a work situation, like a team meeting, you don't want to be completely silent. How often should you speak up?

Cary Pfeffer, a speaking coach and media trainer, shared an example of the appropriate amount of time to talk in a meeting with six people:

"I would suggest a good measure would be three contributions over an hour-long meeting from each non-leader participant. If anyone is talking five/six/seven times you are over-participating! Allow someone else to weigh in, even if that means an occasional awkward silence. Anything less seems like your voice is just not being represented, and anything over three contributions is too much."

Ultimately, the WAIT method is about taking a second to make sure you're not just talking to hear yourself speak. It helps ensure that you have a clear goal for participating in the conversation and that you're adding value for others. Knowing when and why to say something is the best way to make a positive contribution and avoid shooting yourself in the foot.

Education

Real people share 17 red flags that expose someone trying to appear wiser than they actually are

"Actually referring to oneself as 'smart' in general is often a good indicator too."

low intelligence, low iq, iq lower, signs of low intelligence, not smart, not very smart

A man looks confused.

People who struggle with intellectual functioning, often described as having a low IQ, may also be considered to have low intelligence. Determining low intelligence is not always easy or obvious, so people on Reddit shared their thoughts on the signs that can indicate it.

One observant Redditor shared their insight, writing that a sign of low intelligence is "actually referring to oneself as 'smart' in general is often a good indicator too." The comment is an example of the Dunning–Kruger effect, first described in 1999 by psychologists David Dunning and Justin Kruger, which found that people with lower IQs tend to overestimate their intelligence, while those with higher IQs often underestimate it.


"Those with limited knowledge in a domain suffer a dual burden: Not only do they reach mistaken conclusions and make regrettable errors, but their incompetence robs them of the ability to realize it," the psychologists wrote, according to Psychology Today.

17 signs of low intelligence, according to Redditors

"When presented with an statement that generalizes something, they will use an anecdote as a counterexample and think that it completely refutes the statement. Example: travelling in an airplane is generally safer than in a car. 'Actually that's not true, I know someone who died in an airplane crash.'" - Traditional_Rub_9828

"Refusal to learn, grow and change your views from evidence provided." - Userdataunavailable

"Confusing 'being loud' with 'being right.' The loudest person in the room is rarely the smartest." - Kernel_Slasher

"Actually referring to oneself as 'smart' in a general is often a good indicator too." - loku_gem

"Believing anything they see on social media." - Fabulous_Ady

"Lack of curiosity. Thinking they know it all." - Disastrous-Sky-8484

- YouTube www.youtube.com

"Further than a lack of curiosity is never asking questions. It was something I heard about gorilla researchers who taught them sign language that in the years of gorilla sign language communications they never had a gorilla ask a question of a human. That simple process of recognizing you don't know/have something you want, understanding someone else likely does know what you want, and asking them actually takes a lot of brain power. Some parrots and exceptionally smart dogs can hit that threshold... And some very cognitively limited humans do not." - MildGenevaSuggestion

"They get annoyed by people who act curious, too. About anything. 'Why do you care?' 'Who cares?' Idk man, it's just interesting. Why shouldn't I care?" - Belle_Juive

"Not realizing that everything has nuances." - SecretHuckleberry720

"Refusing to consider they might be wrong." - Marry_Ennaria

"Not being able to understand or engage with hypotheticals. It is a meme online but that is actually a sign of low intelligence. Individuals with IQs under 90 often struggle with conditional hypotheticals—such as 'How would you feel if you hadn't eaten dinner?'—responding with factual rebuttals like 'But I did eat dinner.'" - Emergency-Resist-730

@baxate_carter

Even more low IQ traits from a year ago

"Severe impairment in metacognition - that is, a persistent inability to recognize one's own errors in thinking, monitor one's own reasoning, or adjust beliefs/behavior even when presented with clear contradictory evidence." - DiamondCalvesFan

"Ironically, Always having an answer. There is a lot of power in saying 'I don't know'." - Loose-Cicada5473, mattacular2001

"People who mock others instead of trying to understand them. Curiosity is usually a sign of intelligence." - cutiepie_00me

"Repeating the same mistakes and blaming everyone else." - Luckypiniece

"Bragging that you haven't read a book since high school." - tiger0204

"One move chess player. This is like an analogy to how some people think and act and vote. A good chess player is thinking 3 or more moves ahead. a bad one is playing one move ahead only. When people say things like 'Why should I pay school taxes if I don't have any kids!?' they are playing one move without thinking ahead. Better schools means a more educated populace means less crimes and more economic opportunity for your area, thus it benefits everyone whether they have kids or not." - ChickenMarsala4500

arthur c. brooks, harvard, psychology, happiness research, bucket list

Harvard researcher Arthur C. Brooks studies what leads to human happiness.

We live in a society that prizes ambition, celebrating goal-setting, and hustle culture as praiseworthy vehicles on the road to success. We also live in a society that associates successfully getting whatever our hearts desire with happiness. The formula we internalize from an early age is that desire + ambition + goal-setting + doing what it takes = a successful, happy life.

But as Harvard University happiness researcher Arthur C. Brooks has found, in his studies as well as his own experience, that happiness doesn't follow that formula. "It took me too long to figure this one out," Brooks told podcast host Tim Ferris, explaining why he uses a "reverse bucket list" to live a happier life.


bucket list, wants, desires, goals, detachment Many people make bucket lists of things they want in life. Giphy

Brooks shared that on his birthday, he would always make a list of his desires, ambitions, and things he wanted to accomplish—a bucket list. But when he was 50, he found his bucket list from when he was 40 and had an epiphany: "I looked at that list from when I was 40, and I'd checked everything off that list. And I was less happy at 50 than I was at 40."

As a social scientist, he recognized that he was doing something wrong and analyzed it.

"This is a neurophysiological problem and a psychological problem all rolled into one handy package," he said. "I was making the mistake of thinking that my satisfaction would come from having more. And the truth of the matter is that lasting and stable satisfaction, which doesn't wear off in a minute, comes when you understand that your satisfaction is your haves divided by your wants…You can increase your satisfaction temporarily and inefficiently by having more, or permanently and securely by wanting less."

Brooks concluded that he needed a "reverse bucket list" that would help him "consciously detach" from his worldly wants and desires by simply writing them down and crossing them off.

"I know that these things are going to occur to me as natural goals," Brooks said, citing human evolutionary psychology. "But I do not want to be owned by them. I want to manage them." He discussed moving those desires from the instinctual limbic system to the conscious pre-frontal cortex by examining each one and saying, "Maybe I get it, maybe I don't," but crossing them off as attachments. "And I'm free…it works," he said.

- YouTube www.youtube.com

"When I write them down, I acknowledge that I have the desire," he explained on X. "When I cross them out, I acknowledge that I will not be attached to this goal."

The idea that attachment itself causes unhappiness is a concept found in many spiritual traditions, but it is most closely associated with Buddhism. Mike Brooks, PhD, explains that humans need healthy attachments, such as an attachment to staying alive and attachments to loved ones, to avoid suffering. But many things to which we are attached are not necessarily healthy, either by degree (over-attachment) or by nature (being attached to things that are impermanent).

"We should strive for flexibility in our attachments because the objects of our attachment are inherently in flux," Brooks writes in Psychology Today. "In this way, we suffer unnecessarily when we don't accept their impermanent nature."

What Arthur C. Brooks suggests that we strive to detach ourselves from our wants and desires because the simplest way to solve the 'haves/wants = happiness' formula is to reduce the denominator. The reverse bucket list, in which you cross off desires before you fulfill them, can help free you from attachment and lead to a happier overall existence.

A lighthearted moment turns bittersweet with a painful realization.

Parenting is full of bittersweet moments. Every milestone toward independence—walking, talking, the first day of school—marks the end of something precious and fleeting, a time when parents are their children's entire world. So while these firsts are, of course, joyful, it's completely natural for parents to feel a sense of grief.

One such moment happened recently for Nick Gorman while he was filming his daughter playing in a puddle for the first time.


The now-viral clip, posted to TikTok, seems lighthearted enough. Gorman encourages his little one to splash in the water, and when she does, he gushes, "You know what this means? You're officially a kid. You're no longer a baby."

The phrase clearly hit harder than Gorman thought it would, because in the caption he wrote, "Well that realization hurt."

@nick.gorman8 Didn’t realize what I’d said until I watched the video later on…woof! #kiddos #toddlersoftiktok #aww #kidsoftiktok #dad ♬ These Memories - Hollow Coves

It's a realization that's pretty darn universal, as indicated by the thousands of other parents who chimed in on the TikTok video with their own similarly wistful stories:

"Today I heard my daughter getting into the Pop-Tarts while I was doing the dishes and dried my hands waiting for the inevitable 'daddy will you open this?' And then minutes went by, and silence. Curious, I poked my head around the corner and saw her eating them happily. She saw me and announced that she did it herself. I was so proud. But I still move the box up another shelf because I am not ready to stop helping her."

"My daughter used to call ketchup 'dip dip.' One day I asked if she wanted dip dip and she said 'it's ketchup mom.' My heart broke."

"My daughter used to hide from me when I'd get home from work. Came home expecting some elaborate hiding spot but she was just watching tv."

"One day I realized my babies quit calling me dada, and started saying daddy, and that was hard, but when I realized they had switched from daddy to dad that one had me in tears."

Experts seem to agree that when it comes to navigating these closing chapters, parents should permit themselves to feel whatever conflicting emotions arise and remember that it's a natural part of the process.

It's also important to remember that good things are still on the horizon. Every season brings its own special gifts and cherished memories. Even when kids finally leave the house to start their own adult lives, arguably the most bittersweet transition of all, parents are given the chance to explore other aspects of their identity that may have gone dormant during the more active days of parenthood.

Even Gorman seems to have recognized that his realization isn't entirely painful. In an interview with Newsweek, he shared, "While it's sad she's growing up, and we're already seeing our time with her pass, it's exciting at the same time to see her grow and experience new things—which is why I wanted to become a parent in the first place."

Nobody becomes a parent expecting things to become simpler. But most would argue that the trade-off is beyond worth it. And stories like these can remind parents that they're not alone in whatever feelings they're experiencing.

Researchers tested 6 brands of bottled water against tap water, and there was a clear winner

New technology allowed them to analyze the water in ways they never could before.

Ever since bottled water became popular in the 1990s, there has been a vigorous debate over whether it's healthier to drink bottled water or tap water. Bottled-water aficionados often claim it's purer than tap water because it's traditionally marketed as being "from the source" or having come from an untouched stream. That has to be cleaner than water that reaches your home after traveling from God-knows-where through city pipes, right?

What many people don't realize is that bottled water isn't regulated as stringently as tap water. Tap water is overseen by the Environmental Protection Agency (EPA), which requires more frequent testing and stricter disinfection standards. Bottled water is regulated by the Food and Drug Administration (FDA) as a food product.


Tap water found to have fewer microplastics than bottled water

A recent study from The Ohio State University (OSU) delivered another big victory for Team Tap, finding that after testing six brands of bottled water against tap water from four water treatment plants, bottled water contained more than three times as many microplastics as tap water. The big problem is that plastic bottles can shed tiny plastic particles, smaller than a speck of dust, into the water when temperatures change, the cap is removed, or the bottle tumbles around in a purse or the back seat of a car.

tap water, kitchen water, boy drinking, thirsty boy, kitchen sink A boy drinking from the kitchen sink.via Canva/Photos

The tests revealed that the amount of microplastics in bottled water ranged from 2.6 to 11.5 million particles per liter, while tap water ranged from 1.6 to 2.6 million particles per liter. In the best-case scenario, tap water contains similar levels of microplastics, but in the worst-case scenario, bottled water contains more than seven times as many.

The researchers were surprised by their findings because nanoplastics are so small that they've been hard to quantify in the past.

"This lack of knowledge primarily reflects limitations in the methods to isolate and analyze the nanoplastics," said Megan Jamison Hart, a PhD candidate at OSU and the study's lead researcher. "In this study, we developed and validated a novel method for isolating MNPs [micro- and nanoplastics], allowing for the determination of their concentrations using scanning electron microscopy and identification using optical photothermal infrared spectroscopy (OPTIR)."

Are microplastics harmful to humans?

Much more research on microplastics is needed to determine their potential harm to humans. Studies have linked microplastics to impaired immune function, increased inflammation, and cellular damage in animals. Researchers believe that larger nanoplastics pass through the digestive tract and are eventually excreted. Smaller nanoplastics, however, may move into human tissues and even enter the brain.

"While we don't really fully understand the human health risks associated with nanoplastic exposure, it's still better to try and mitigate that risk because evidence indicates that they do cause problems, even if we're not fully aware of what those are yet," said Hart.

Given that scientists have yet to determine the harm that micro- and nanoplastics can cause in our bodies, they believe it's best to avoid them as much as possible.

"We can make educated choices to try and reduce our daily exposure to these harmful chemicals," said Hart. "For the average person who is thirsty and wants a drink, the best way to do that would be drinking it straight out of the tap rather than grabbing pre-bottled water."

Hart told StudyFinds that the best thing to do is ditch bottled water and instead drink filtered tap water from a reusable metal bottle.

"This has definitely changed my own drinking habits," she said. "I was primarily a tap water drinker before, knowing that disposable bottles were bad for the environment, but this is something I am even more adamant about now, and I swapped my reusable plastic bottle for a reusable metal one."
