A recent study published in Science reveals that genetics plays a crucial role in human lifespan, with intrinsic mortality heritability estimated at 55%—more than double prior estimates of 15-33%. Conducted by researchers from Israel’s Weizmann Institute of Science and Sweden’s Karolinska Institutet, this study challenges previous beliefs about the balance between genetic and environmental influences on longevity. The findings could pave the way for personalized approaches to healthy aging, highlighting the need for continued research into genetic factors affecting lifespan.
