Life Expectancy
House mice usually live under a year in the wild, due to a high level of predation and exposure to harsh environments. In protected environments, however, they often live two to three years. The Methuselah Mouse Prize is a competition to breed or engineer extremely long-lived laboratory mice. As of 2005, the record holder was a genetically engineered mouse that lived for 1819 days (nearly five years). Another record holder that was kept in a stimulating environment but did not receive any genetic, pharmacological, or dietary treatment lived for 1551 days (over four years).

Famous quotes containing the words life and/or expectancy:
“The fate of the poor shepherd, who, blinded and lost in the snow-storm, perishes in a drift within a few feet of his cottage door, is an emblem of the state of man. On the brink of the waters of life and truth, we are miserably dying.”
—Ralph Waldo Emerson (1803–1882)
“O, what a noble mind is here o’erthrown!
The courtier’s, soldier’s, scholar’s,eye, tongue, sword,
Th’ expectancy and rose of the fair state,
The glass of fashion and the mold of form,
Th’ observed of all observers, quite, quite down!”
—William Shakespeare (1564–1616)
