Alert PETA. Trouble ahead. The naked mole rat is a useful model for aging and cancer. "The strictly subterranean naked mole rat lives as long as 30 years and shows negligible senescence, no age-related increase in mortality, high fertility until death, and resistance to spontaneous cancer and experimentally induced tumorigenesis. They also live in full darkness at low oxygen and high carbon dioxide concentrations and are unable to sustain thermogenesis or feel certain types of pain. " Nature, via JAMA, Dec. 7, 2011
