Somatic mutations are pegged as the bottleneck cutting a 1,759-year ceiling to 156

Claim

Aging researchers pegged somatic mutations as the bottleneck, with post-mitotic neurons and heart cells that never divide cutting a theoretical non-aging lifespan of 1,759 years to about 156, still roughly double today's span, while Eli Lilly bet $2.8 billion on a Phase 3 nasal spray in the largest psychedelics deal in pharma history.

Reported metric: 156 years / $2.8B
