You may have forgotten when you received your period, but think back to that horrible day when your monthly friend first arrived.
Were you a late bloomer or the first female in your friend group to "grow up"?
Women who had their first period later in life are more likely to live longer lives, according to a survey conducted by researchers at the University of California, San Diego.
Researchers examined data from 16,000 postmenopausal women collected by the Women's Health Initiative during the investigation.
In doing so, they discovered that both the age of the first period and the age of menopause affect general health and longevity.
According to the study, having your period at the age of 12 and up, as well as starting menopause after the age of 50, is linked with living a longer life.
