"Jenni E. Pettay of the University of Turku in Finland and her colleagues analyzed medical records of four generations of Finns born between 1745 and 1903. They found that mothers and daughters tended to share a number of similarities, including the age at which they first gave birth and the number of children they had who survived to adulthood. Across generations, a family's lifespan was relatively consistent, with women who delayed childbirth living longer than women who had their first child at a younger age. In addition, women who waited longer between births lived longer than did mothers who gave birth in quick succession. For males, meanwhile, there was no significant link between the age of first fatherhood and longevity."
