Birthrates have been declining for years here in the U.S., but for those 45 and up they’re increasing by double digits. Actress Cameron Diaz and her husband, 47-year-old Benji Madden just announced the birth of their son, Nautus. The couple has been very private about the details of their growing family, but they are on a sizable list of notable, older parents. While some people may have negative comments about the impact to the child, many recent studies have found that having children later in life, thanks to modern technology, has increased health benefits for both the parents and the child.
