Giving birth ages women faster than smoking, obesity: Study
Having children adds eleven years to a woman's biological age and accelerates the ageing process more than smoking and obesity, according to a US-based study of over 1,900 women aged 20-44. The researchers studied the length of telomeres, the end section of a chromosome associated with longevity, and found motherhood shortened the telomeres by 4.2%, more than smoking and obesity.
