Lifespan, longevity, and ageing
Maximum longevity: 4 years (captivity) Observations: A major model of biomedical research, mice are amongst the fastest ageing mammals exhibiting a variety of physiological, functional and pathological changes with age. The record longevity for normal mice is 4 years, belonging to one wild-derived specimen (Miller et al. 2002). Mutant and caloric restricted mice, however, can live over 4 years (Bartke and Brown-Borg 2004), though these are not deemed suitable for species comparisons. Record longevity belongs to a mutant dwarf mouse that lived 1819 days (Andrzej Bartke, pers. comm.). Smaller mice tend to live longer (Miller et al. 2002).
