An increase in mitochondrial superoxide extends lifespan in C. elegans but not by hormesis?

Edit: I was forwarded a convincing skeptical argument that because C. elegans lacks dividing cells and DNA repair genes that function like higher organisms likely because it doesn't live as long, it might have a greater protective response to superoxide. Longer-living organisms have cancer to worry about so cells may allow senescence to occur to freeze cells in a non-dividing state.
