If a woman doesn’t want to age faster, it’s better to have few children. In fact, researchers from the University of George Mason found out that most women who gave birth to a child have shorter telomeres than those who didn’t. It means that the parts of chromosomes responsible for DNA protection get smaller with age.
Women from different ages took part in the study, and it turned out that the more kids a woman has, the shorter her telomeres become.
Thus, this can be the result of different reasons like stress, for example.
