24 Apr 2025
You are familiar with the advice that you shouldn’t go grocery shopping when you are hungry because you will spend more money and buy more junk. However, that’s just a piece of story. Hunger and shopping are related in other ways. This episode begins by explaining how. https://phys.org/news/2015-03-hungry-people-food.html#google_vignette The idea that spending too much time on your phone, tablet or computer is bad for you has become conventional wisdom. But is that true? What does the research say about this? It turns out it's not black and white, there are shades of gray worth understanding. Here to explain this is Jacqueline Nesi. She is a psychologist and assistant professor at Brown University who writes the popular weekly newsletter Techno Sapiens (https://technosapiens.substack.com), which provides tips to manage your screen time better. She has published over 50 peer-reviewed publications related to technology use and has appeared on CNBC, CNN, and NPR. Your body is an amazing collection of processes and systems that all work to keep you alive and moving. Most of us have no idea what goes on inside of us to make it all happen so, here to explain some of it and unravel a few mysteries of the human body and explain why we can’t live forever, how the body defends itself, why we need to sleep and so much and more is Dr. Darragh Ennis. He is a scientist and researcher who has worked at the University of Oxford and the University of Glasgow and he is author of the book The Body: 10 Things You Should Know (https://amzn.to/42ApkC5). Have you heard the word “halfalogue? It’s when you hear someone else talking on their phone but you are hearing only their side of the conversation.

I'm Anne Foster, host of the feminist women's history comedy podcast, Vulgar History. And every week I share the saga of a woman from history whose story you probably didn't already know and you will never forget after you hear it. Sometimes we reexamine well-known people like Cleopatra or Pocahontas, sharing the truth behind their legends.
Sometimes we look at the scandalous women you'll never find in a history textbook. If you can hear my cat purring, she is often on the podcast as well. Listen to Vulgar History wherever you get your podcasts.
Today on Something You Should Know, how hunger affects what you buy. Not just groceries, everything you buy. Then, some facts and myths about screen time and video games.
You know, there was a big concern for a while about violence in video games. Generally, the research does not support any long-term links between playing violent video games and violent or aggressive outcomes in the long term.
Also, why listening to other people talk on their phones can drive you nuts. And the amazing ways your body works, your heart, your immune system, your brain.
Your brain washes itself at nighttime. There's been studies where they've watched people when they're going to sleep, and they've seen pulses of cerebrospinal fluid going over the brain during sleep. They really think that this maintenance time of sleep helps remove bad things for your brain, toxin buildup.
All this today on Something You Should Know.
We are Theresa and Nemo. And that's why we switched to Shopify.
The platform we used before Shopify needed regular updates, which sometimes led to the shop not working.
