Skratch Labs Field Study Bottle SDM and a large openingThis bottle shows. Nothing Happens in Isolation. It starts simple. Water. Sodium. Carbs. A bottle. A body. A plan. Separate pieces. Clean variables. Easy to track. But the moment you move, everything collapses together. Effort changes heat. Heat changes sweat. Sweat changes sodium lost. Sodium changes thirst. Thirst changes decisions. Decisions change outcome. Nothing stays separate for long. This is the system. Not linear. Not controlled. Not fixed.
