C. elegans worms live longer when their capacity to sense food chemically is impaired; conversely, their lifespan is shortened even on CR if they are allowed to sense but not ingest food . Calorically restricted fruit flies exposed to food-derived odors don’t live as long as the same CR flies without food odors . The central role of signaling implies that there is latent capacity for extending lifespan that the body does not always deploy, but must be instructed to do so with signals that can be triggered by environmental cues.
