Having children can make women's telomeres seem 11 years older

(George Mason University) A study by George Mason University Researchers found that women who have given birth have shorter telomeres than those who haven't. Telomeres are the end caps of DNA on our chromosomes, which help in DNA replication and get shorter over time. The length of telomeres has been associated with morbidity and mortality previously, but this is the first study to examine links with having children.
