**The Decay Rate Is 15% Per Hour—Why This Hidden Trend Matters in the U.S. Today** What happens when something fades at a steady 15% every hour? The impact might feel slow at first, but over time, it adds up—sometimes faster than expected. The decay rate of 15% per hour describes exactly how much of an element, resource, or signal diminishes hourly, leaving 85%—or 0.85—of its previous value. This concept, once confined to niche science and technology circles, is now drawing attention across the U.S. as people explore its relevance in digital engagement, personal well-being, and long-term trends. In digital spaces, content decay shapes how users experience information.

Understanding this 85% retention pattern can help creators, businesses, and individuals design strategies that sustain relevance longer. ### Why This Decay Rate Is Gaining Attention Across the U.S.
