From the New York Times:
Ann Logan and her three sisters grew up in Delaware; none of them have children. Their stepbrother and seven first cousins on both sides are childless, as well. “Each of us had different reasons,” she told me.
Ms. Logan, the eldest sister at 63, doesn’t regret her decision not to be a parent, but she does worry about the future as she and her relatives all age.
For now, divorced and living in Manhattan, she’s a busy lawyer with good friends, caring neighbors and an Abyssinian cat named Henry. When she needed a double knee replacement a couple of years ago, a friend flew in from Fort Worth to help her, followed by another friend from Washington, followed by one of her sisters. Then neighbors came by to be sure Ms. Logan was taking her medications and to encourage her to get up and walk.
