Rejection, or even the thought of it, can strike fear into our hearts, and leave a bad taste in our mouths. It often leads to a mix of sadness, shame, anxiety, and anger — along with nagging questions. What's wrong with me? Why did this person not like me? Why didn't I win this award? Why didn't I get the job? But it doesn't have to be that way, and there's a lot we can learn from not making the cut. On this episode, we explore the experience of rejection — what it feels like, how it functions, and the lessons we can draw from it.We'll hear from a fear and anxiety researcher about the evolutionary roots of anxiety — and why asking someone out on a date can feel like a life-or-death situation. Then we'll explore a common experience among people with ADHD, known as rejection sensitive dysphoria (RSD), and hear how one future physician dealt with the worst rejection of her life.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

For most of the big moments in life, we have rituals — proposals, weddings, births, graduations, and anniversaries. We know how to talk about them, how to celebrate them, how to honor them. But there's one moment we all face that lots of people don't know how to deal with: dying.In fact, a majority of Americans avoid end-of-life planning, even though most say it's important. Losing a loved one — not to mention facing your own mortality — is a hard reality to contemplate. So how do we go about having those tough conversations about the end of life? Is there a "right" way to talk about it? Can we really prepare for death and the grief it brings in a way that is helpful? And does it get any easier when people know it's coming?On this episode, we explore how we talk — or avoid talking about — death; the funny, tender, and hopeful moments that arise in those conversations; and how we can best support our loved ones in their final moments. We hear stories about two very different approaches to confronting death, how death doulas help usher their patients into the unknown, and new approaches to dealing with prolonged grief.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Flying saucers, little green men, and the X-Files — for years, that's what most people associated with unidentified flying objects, or UFOs. They were the stuff of sci-fi and supermarket tabloids, conspiracy theories and punchlines.But ever since a bombshell article in The New York Times several years back documented confirmed sightings by navy pilots, UFOs — or UAPs, unidentified aerial phenomena, as they've been rebranded — have been slowly migrating into the mainstream.Today, it's not uncommon to find scientists, elected officials, and decorated members of the military talking publicly about UFOs. Records are being unclassified, research projects launched — there was even a Congressional hearing dedicated to UFOs. And beneath it all lies the age-old question: Are we alone?On this episode, we explore the past — and future — of the search for life on other planets. We talk with a historian about how attitudes towards UFOs have changed over the decades; we look at how scientists are approaching the study of UFOs; and we hear the strange story of a sighting back in the 90s that begs the question of what — and who — we believe.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

Dealing with a serious or chronic health condition is hard enough — but what happens when that condition comes with moral judgment? That's the case for millions of people around the world. From obesity to lung cancer, sexually transmitted diseases to mental illness, stigmatized conditions are shrouded in shame and blame that can not only hinder treatment — but ruin lives.On this episode, we explore stigmatized health conditions — how they earn their reputations, affect the lives of patients, and complicate efforts to treat them. We hear about the flawed effort to track down the origin of the HIV epidemic in the U.S. that inadvertently introduced a new term into our language. We explore what researchers say is behind the "blame and shame" game in public health, and we find out why a man diagnosed with antisocial personality disorder says his condition isn't always as scary as people think.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

In 1978, NASA recruited six candidates out of thousands of applicants for a special, groundbreaking mission: to become the first American women in space. Over the next few years, the six women would endure sexism, grueling training, and unending scrutiny from the media. In her new book, "The Six: The Untold Story of America's First Women Astronauts," author Loren Grush explores the stories of these female pioneers, along with the longer history of women's fight for inclusion in the male-dominated world of NASA.On this episode, we talk with Grush about how America's first female astronauts came to be, their journeys and challenges, and what kept them committed to their mission. Later, we hear from another space pioneer — a Navajo NASA engineer who says his childhood in Arizona prepared him for his work studying Mars.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

It sneaks up on us while we're sitting in traffic, or waiting at the doctor's office, or doing our taxes — boredom, that restless feeling of dissatisfaction that arises when we harbor "the desire for desires," as Leo Tolstoy said.At the same time, we're living in an age of never-ending stimulation, all at our fingertips — texting, social media, 24-hour news, and streaming galore. But despite this constant content consumption, we're still getting bored — maybe even more so than ever. We find ourselves hopping from tab to tab, scrolling through Instagram while watching a show, tuning out of meetings to check our email. And now some researchers are worried that all this stimulation could be changing our brains.On this episode, we look at boredom in the age of information overload, and whether or not it's really good for us and our brains. We hear stories about what happened when two reporters quit their digital addictions for four weeks, a monk who took his search for boredom to the ultimate extreme, and why there's value to the slow pace of baseball.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
