We all want to live longer and thanks to medical technologies our life expectancies have dramatically increased. Which would be handy if we could actually enjoy the extra years. Unfortunately a study of long-lived mutant C. elegans by scientists shows that the genetically altered worms spend a greater portion of their life in a frail state and exhibit less activity as they age than typical nematodes. These findings suggest that genes that increase longevity may not significantly increase healthy lifespan and point to the need to measure health as part of aging studies going forward.
