"Nature...abounds in organisms that can and do reversibly arrest their essential life processes, in some cases for several years at a time. Scientists describe these phenomena by a variety of terms--quiescence, torpor, hibernation, among others--but all represent different degrees of suspended animation, a dramatic reduction of both energy production (metabolism) and energy consumption (cellular activity). What is more, organisms in this state enjoy extraordinary resistance to environmental stresses, such as temperature extremes, oxygen deprivation and even physical injury." (SCIENTIFIC AMERICAN) This article describes suspended animation, examines how some animals come close to this state when they hibernate and explains the difficulty in applying this state to humans who need a steady supply of oxygen to survive.
