What Happens To Your ENERGY As You Get Older?" — Feynman's Unsettling Answer

Описание: Feeling tired is often dismissed as a normal part of getting older. You eat similar food, sleep roughly the same hours, and follow familiar routines, yet your energy no longer feels the same. What if this change is not just biological wear and tear, but something the fundamental laws of physics have predicted all along?

Every day, the human body produces and recycles more than 50 kilograms of a molecule called ATP, the primary carrier of usable energy inside cells. This amount exceeds total body weight, yet it is generated continuously to keep tissues functioning. The system responsible for this process is highly efficient, but it is not permanent. From the moment you are born, the machinery that converts food into usable energy begins a slow, unavoidable decline.

At first glance, this appears to be a simple metabolic issue. However, when examined more closely, it reveals a deeper connection. The same physical laws that govern engines, stars, and heat flow also govern the cells in your body. These laws describe how energy moves, how it degrades, and why no system can operate at perfect efficiency forever. Applied to biology, they offer an uncomfortable but powerful explanation for fatigue, aging, and decline.

In this video, we explore how energy, entropy, and aging are connected, through the lens of thermodynamics. Drawing inspiration from the teaching style and ideas of Richard Feynman, along with Erwin Schrödinger’s What Is Life? and modern research on mitochondrial function, this documentary examines aging as a physical process rather than a purely biological mystery.

What emerges is not a medical lecture, but a physics-based perspective on why the body changes over time. It is a lesson about limits, efficiency, and the cost of maintaining order in a universe that naturally moves toward disorder.
