A Boston University School of Medicine study published in the journal Menopause found that women who are able to have kids naturally later in life (after age 33) have a higher chance of living to extreme old age than those who had their last child before the age of 30. Imagine that. Women who had their last child after the age of 33 were two times as likely to live to 95 or older, compared to those who had their last child by 29. “If you physically delay having children, that’s not going to help with longevity,” Paola Sebastiani, a Boston University biostatistics professor and study co-author, told OZY.

Sebastiani and her team analyzed data from the Long Life Family Study, a survey of 551 families, many of whose members lived well into their senior years. They determined the ages at which 462 women had their last child and how long they ended up living. The researchers discovered that not only did more mature mothers have a long life, but these older mothers were twice as likely to live to 95 or older than those mothers who had their last child by age 29.

Women with such variants might be able to bear children for a longer period of time, increasing their chances of passing these genes down to future generations. Another of the study’s authors, Dr. Thomas Perls, said, “This possibility [of slow aging genetic variants] may be a clue as to why 85 percent of women live to 100 or more, while only 15 percent of men do.” It’s all about genes and passing those good genes down to the next generation. Only good can come when you wait until you’re older to have children. You’re more grounded in who you are. Maybe you and your spouse deiced to enjoy just being with each other before you had kids. Maybe you enjoyed playing the cool aunt with all of your friend’s kids for a while before you decided to have some of your own. Whatever the reason, know that you get the chance to live longer with your children when you wait.
