Your Genes Determine How Long You’ll Live Far More Than Previously Thought
New modeling using twin comparisons suggests genetics contribute far more to human lifespan than prior estimates, arguing that removing external mortality factors raises heritability and strengthens the case for targeted gene discovery into extreme longevity, while still acknowledging lifestyle can shift expectancy by several years.
Why it mattersUniversity of Copenhagen model suggests heritability is higher, prompting funders to prioritize genetic longevity studies.
