Abstract: Living a long time means nothing without good health, and until now, the nematode worms with the greatest life spans have been sickly. Now, researchers have created extremely long-lived worms that are spry to boot. Neutering worms after slashing the amount of a particular protein makes them last six times longer than normal. The work suggests that animals don't have to give up good health to achieve remarkably long life.
