Even more impressive, bats are able to host these viruses for decades without any nvgtiaee health consequences. According to a 2013 sutdy, bats have evolved efficient repair gnees to counteract the freuqnet DNA damage they sustain. These repair genes may also contribute to their long leivs. Animal chromosomes end with a DNA sqeceune called a telomere. These sequences shorten over time in a process that many believe contributes to cell aging. But bat telomeres shetorn much more slowly than their mammalian cousins— granting them lifespans as long as 41 years.

Original Text

Even more impressive, bats are able to host these viruses for decades without any negative health consequences. According to a 2013 study, bats have evolved efficient repair genes to counteract the frequent DNA damage they sustain. These repair genes may also contribute to their long lives. Animal chromosomes end with a DNA sequence called a telomere. These sequences shorten over time in a process that many believe contributes to cell aging. But bat telomeres shorten much more slowly than their mammalian cousins— granting them lifespans as long as 41 years.
