Ever stood at the edge of an overlook and heard a little voice say, "What if I just jumped?" You're not alone, and you're not broken. It has a name: the call of the void.
In this episode of Barry Outdoors, I dig into the research on the "high place phenomenon" (the 2012 Florida State study and follow-ups in Germany and Iran) and why your brain's safety system may be behind that strange pull at the edge. I share my own moments on a river gorge and in the Porcupine Mountains in Michigan's Upper Peninsula, explain what it isn't, and share my 3 tips for edges on the trail.
If these thoughts stick around, keep coming back, or come with any real wish to hurt yourself, please talk to someone. In the U.S., call or text 988, the Suicide & Crisis Lifeline, any time: https://988lifeline.org
