You Won’t Believe How Long Lab Rats Actually Live: Shocking Life Expectancy Revealed! If you thought lab rats had short, fleeting lives, think again — new research is completely transforming our understanding of rodent longevity. Recent findings reveal that many lab rats now live far longer than previously documented, shattering long-held assumptions about their life expectancy. ### The Surprising Lifespan of Lab Rats Contrary to older estimates suggesting lab rats typically live only 2 to 3 years, scientists have now uncovered evidence showing some species can live 5 to 7 years or even longer in controlled environments. This unexpected extension challenges common beliefs about rodent senescence and opens exciting new avenues for aging research.
