- Disturbing mitochondria can change a cell’s gene expression independently of ATP because mitochondrial perturbations release signaling factors that alter transcription and growth even when energy synthesis is preserved.

- A finite body energy budget forces trade-offs because when illness, injury, or chronic stress draws resources to one process, other systems and conscious experiences like attention and mood suffer.

- Social rules that push right-hand use can amplify biological bias because assigning tasks like eating to the right and hygiene to the left reduces contamination risk and stabilizes rightward practices across generations.

- Rare left-handers keep appearing because their scarcity gives them a tactical surprise advantage in one-on-one fights and sports, exploiting opponents who are trained mostly against right-sided moves.

- If a pulling apparatus cannot reach high enough strain rates, the product viscosity times strain rate stays below the fracture threshold, so lower-viscosity liquids may never exhibit fracture under that experimental limit.

- Without elasticity to absorb and slow energy release, a crack can accelerate until inertia and cohesion are the only limits, which lets fractures reach the maximum speed allowed by physics.
