32. Why can organ-specific strategies be more beneficial than universal interventions?

Organ-specific interventions target weak links that disproportionately determine morbidity and mortality, without globally rebalancing the organism. Because they relieve bottlenecks, they can yield benefits with fewer systemic tradeoffs. However, organ-specific interventions are expected to change biological age substantially only when the targeted organ is a limiting weak link or a source of systemic burden. An important practical path to extending healthy life is therefore to identify the most aged organs/systems in each individual and apply interventions tuned to those weak links.
