Behavioral scientists found that people without children develop a relationship to mortality that is psychologically distinct. Without biological continuation, they must construct meaning through contribution, connection, and presence rather than lineage, and that construction is both harder and, when successful, more intentional than most people realize.

Without biological continuation, people who never have children are forced to build their own relationship with mortality from scratch, and the psychological architecture that requires turns out to be both more fragile and more deliberate than most of us assume.
