Growth Health Diagnostic

Endotherms burn 10x more energy than ectotherms at the same body mass — running hot is powerful but metabolically expensive. If burn outpaces intake, hypothermia follows.

Bacterial cultures in exponential growth phase accumulate more DNA replication errors per generation. Speed of reproduction and quality of reproduction are in direct tension.

Termite mounds maintain internal temperature within 1°C despite 40°C external swings — but only when ventilation architecture keeps pace with colony growth. Infrastructure debt shows up as thermal instability.

Autoimmune diseases occur when the immune system attacks the body's own tissues despite increased immune spending. More retention spend with rising churn suggests you're attacking your own customers.

Redwoods invest 60% of energy in roots that no one sees. The visible canopy is supported by an invisible majority — and the ratio is non-negotiable.

Camels survive 7 days without water by running reserves built during abundance. Runway is not a financial metric — it's a biological survival strategy measured in metabolic reserves.

Bacterial resistance to antibiotics can evolve in 11 days under lab conditions. If your advantages can be replicated that fast, they aren't advantages — they're temporary head starts.

Honeybees encode foraging routes in waggle dances so any bee can replicate the path. Knowledge that lives only in individuals dies when they leave the hive.

Kleiber's Law: metabolic rate scales at the 3/4 power of body mass. Elephants are more efficient per kilogram than mice. Revenue per employee should follow the same curve — if it doesn't, scaling is broken.

Ant colonies above 10,000 workers spend more time in traffic jams than foraging. Coordination costs follow a power law — they don't increase linearly, they explode.

Slime molds double their cell count without increasing problem-solving ability past a threshold. More cells ≠ more intelligence once communication bottlenecks dominate.

Puberty, metamorphosis, and molting are biological inflection points where the old body plan can't support further growth. Missing the transition window means growing into the wrong shape.

Neural signal speed in blue whales limits real-time coordination — their tail doesn't know what their head decided for 2+ seconds. Body size physically slows decision propagation.

Prairie dogs spend 33% of daylight hours on sentinel duty — watching for threats instead of foraging. Past a threshold, vigilance consumes the resources it's supposed to protect.

Predators expend more energy per hunt as prey density drops — the same meal costs progressively more to catch. Rising CAC with flat LTV is ecological diminishing returns.

Sharks must continuously swim or suffocate — but 70% of their evolutionary innovation happened in the first 50 million years. Mature organisms maintain through momentum, not invention.

Veterinarians diagnose by identifying the single limiting organ — the heart, the liver, the kidneys. Every organism has one binding constraint that gates all other functions.

Cancer is growth without purpose — cells replicating without contributing to the organism. The question isn't whether you're growing, but whether growth is serving the whole.

A biologist examining most companies would diagnose gigantism — growth beyond the point where the body plan can support coordination. The prescription is usually architectural, not nutritional.

Circadian rhythms reset every 24 hours regardless of what happened yesterday. Ninety days is roughly one biological quarter — enough time for one full adaptation cycle.
