How GPS Quietly Runs the World & When Illness Has No Obvious Cause

Ever notice when you hear someone talking on the phone nearby it’s hard not to listen? You are only hearing one-side of the conversation and that can drive your brain crazy. It’s not just annoying and distracting it can actually be dangerous. https://now.uiowa.edu/news/2017/06/ui-study-explores-why-cell-phone-use-leads-distracted-driving It’s hard to imagine life without GPS. But now it has become so woven into daily life that most of us never think about it. We use it to navigate, order food, track packages, find rides, locate our phones and even synchronize financial transactions. Yet GPS wasn't created for that. It began as a military technology and evolved into one of the most important—and expensive—infrastructure systems ever built. How does GPS actually know where you are? Why is it free to use? Who pays for it? Is it spying on you? Here to explain is Katherine Dunn, business reporter, editor and author of the book Little Blue Dot: How GPS Shaped the Modern World (https://amzn.to/4uvtk2M). Why is it that millions of people experience chronic pain, fatigue, digestive problems and other ailments that doctors and medical tests often fail to explain? Too often they're told "it's all in your head." But according to psychiatrist Susan Trachman, that phrase badly misunderstands what's happening. The connection between the brain and body is far more powerful than most people realize. Thoughts, emotions and stress can trigger genuine physical symptoms—and understanding how can be the key to finding relief. Susan has spent more than 30 years treating medically unexplained illnesses. She is author of the popular Psychology Today blog and the book It's Not Just in Your Head.

So why do athletes do it? Is it habit? Showmanship? Or is there something else going on? https://www.womenshealthmag.com/fitness/a64691561/grunting-power-output-study/ PLEASE SUPPORT OUR SPONSORS AIR DOCTOR: Head to ⁠⁠https://AirDoctorPro.com⁠⁠ and use promo code SYSK to get $250 off select AirDoctor air purifiers, including the 3500, 4000, and 5500 models.

Curiosity is a powerful engine, and Something You Should Know is built on the idea that a single conversation can shift your perspective in a meaningful way. Host Mike Carruthers, through OmniCast Media, sits down with researchers, authors, and practitioners across a surprisingly wide spectrum-from neuroscience and health to social dynamics and personal finance. The aim isn't just to accumulate facts, but to uncover practical wisdom you can apply directly. You might hear a psychologist explain the simple habit that strengthens relationships, followed by an economist demystifying how to build lasting wealth, and then a physiologist breaking down the real science behind effective fitness. This podcast operates on the belief that improvement is multifaceted; a tip for saving time can be as valuable as understanding a new scientific discovery. Each episode is a self-contained dive into a topic that could very well change your approach to your career, your health, or your daily routine. The tone is conversational and grounded, focusing on actionable takeaways rather than abstract theory. By weaving together insights from the fields of science, education, and self-improvement, the show provides a toolkit for navigating life's complexities. It’s the kind of listening that leaves you with something concrete-a strategy, a new understanding, or a piece of advice that resonates long after the episode ends.
