Summary

Some cars have gullwing doors, like the DeLorean in Back to the Future. They look amazing — but why don’t more cars have them? As you’ll hear, there are several surprising (and practical) reasons why this futuristic design never became mainstream and probably never will. https://www.dacemotorgroup.co.uk/blog/the-history-of-gullwing-doors-and-why-they-were-so-rare If you’ve ever felt truly hopeless, you already understand the extraordinary power of hope — because when it’s gone, everything changes. Hope gives us direction, energy, and purpose. It’s what gets us up in the morning and helps us persevere through uncertainty. Psychologist and researcher Dr. Julia Garcia, author of The 5 Habits of Hope: Stories and Strategies to Help You Find Your Way (https://amzn.to/4hKtWNd), joins me to explore how hope works in the brain, how to build more of it in your life, and why it’s one of the most powerful forces in human psychology. You have a sixth sense — and it’s not psychic. It’s called interoception, your ability to sense what’s happening inside your body. Hunger, thirst, fatigue, and even intuition are all part of this hidden system that connects body and mind. Science journalist Caroline Williams, author of Inner Sense: How the New Science of Interoception Can Revolutionize Your Health (https://amzn.to/4oN8Boo), reveals what researchers are discovering about this remarkable sense — and how tuning into it can improve your health, focus, and emotional well-being. And finally, if you’ve ever had a fruit fly land in your glass of wine, you know how fast they can find you — and ruin a drink. But how do they track it down so quickly, and why does even one tiny fly spoil the whole glass? The answer is both fascinating and a little gross. https://www.livescience.com/7256-fruit-flies-find-wine.html?utm PLEASE SUPPORT OUR SPONSORS!

So our sight and our hearing and our other senses, they

are extroceptive. They tell us about the external world. Interoception tells you what's going on
