36. Can pharmacology slow aging?

Pharmacology can slow aging if it shifts the balance of damage long-term. However, it depends on species, timing of intervention and other factors. Rapamycin highlights this complexity. In mice, it extends lifespan when it is applied only during development, throughout life and even when started late in life, consistent with the idea that modulating nutrient-sensing and growth programs can reallocate resources and reduce pathological changes. Mortality curves after late-life application suggest that rapamycin can shift the log-hazard downward (affecting the intercept) without necessarily altering the slope. Depending on context and endpoint, it may slow aspects of aging, lower risk, or shift physiological state. Drugs like rapamycin can meaningfully change trajectories and synergize with other approaches (diet, lifestyle, regeneration).
