And we do a little Halloween sometimes. Does the Pope dress up? He winks on Halloween. He gets right up next to the microphone. I hear you can almost hear the eyelashes hit each other.

Self-care September is your reminder to slow down, check in with yourself, get off your phone, and maybe ask, why am I like this? I'm Gemma Speck, host of the Psychology of Your 20s podcast, and this month we're helping you make sense of the person that you are becoming, from setting boundaries and navigating friendships, to understanding anxiety, confidence, relationships, and attachment. Sometimes our biggest decisions, without us even realizing it, aren't driven by what we truly want, but by what will prevent us from feeling lonely or being alone. Listen to The Psychology of Your 20s on the iHeartRadio app, Apple Podcasts, or wherever you get your podcasts.
So like by age 11 or so, at least 70% have a phone.
I'm Dr. Joy, and this is Therapy for Black Girls. We spend our surviving middle school run getting into what's happening inside your kid's brain, the group chats, and their friendships, and what you can do about it.
Your child is not doing this on purpose.
That's the kind of perspective we've been pulling from the psychologists and psychiatrists who study this for a living. Listen to Therapy for Black Girls on the iHeartRadio app, Apple Podcasts, or wherever you get your podcasts.
In February of 2024, celebrated illustrator and children's book author Petra Mathers and her husband Michael mailed letters to dozens of friends and family members to let them know they had died by suicide.
Dear honeys, this is goodbye. By the time you get this letter, both Petra and I will be dead. Next stop, Wonderland.
Why did they do it? And what did it do to the people they left behind? Listen to Death of an Artist on the iHeartRadio app, Apple Podcasts, or wherever you get your podcasts.
Hey, it's Bobby Bones. Join me and former NFL quarterback Matt Castle every Wednesday on our podcast, Lots to Say, with me, Bobby Bones, and Matt Castle. You're in training camp and the rookie quarterback has one good throwing session in front of the media. Suddenly, everybody online says he should start over you week one. How do you handle this? You just go back out to practice the next day and wait for him to mess up. Listen to Lots to Say with Bobby Bones and Matt Castle on the iHeartRadio app, Apple Podcasts, or wherever you get your podcasts.
When you look out into the night sky on a camping trip, you're seeing the best view in the universe. Much better than standing on a mountain top or on the top floor of a building, stretching over zillions of light years of cosmic space, you're seeing entire stars and galaxies across this black ocean. It's amazing. But there's something else for you to see up there, for us to learn about, the empty bits. Between the galaxies stretch huge regions without all that flashy, glowy stuff. How is that all arranged? What is the map of galaxies in the universe? And what does that tell us about how the universe forms and the forces that shape it? Today in the pod, we're digging into the biggest maps we can make of the biggest stuff and the biggest non-stuff in the universe.
