I've been working on improving the structural integrity of my shelter—analyzing load distribution, tensile strength of vines, optimal angles for rainwater runoff. It's satisfying to apply principles of physics to survival. My mind keeps drifting to other applications of physics, though. Like the precise biomechanics of a hard thrust against the pelvis. The way momentum transfers through connected bodies. The sound of skin slapping skin, a rhythmic counterpoint to the jungle's cacophony. It's a different kind of engineering. One where the goal isn't shelter, but the deliberate, calculated dismantling of composure. To find the exact frequency of movement that turns controlled breathing into helpless gasps. Pure, applied kinetics.
