Animal & human evidence

From rodent lifespan tails to elderly cohorts

This unit is the outcomes ledger. It gathers the animal lifespan and tumor studies, the long human follow-up cohorts reporting mortality and aging-index benefits, and the immune-endocrine signals, then grades them honestly. The pattern is a real but soft signal, wrapped in design limitations.

By the end you should be able to say exactly why the animal data are moderate, the human data are low-to-moderate, and neither reaches the bar of modern randomized proof.
