Why do almost all versions of Rick across the Citadel share this exact age bracket? The explanation lies in the structural mechanics of the Central Finite Curve.
When C-137 teamed up with the collective council to build the Citadel, they quarantined all infinite dimensions where Rick Sanchez was not the smartest being alive. They also anchored the multiversal ecosystem around a specific existential moment: the period following the death or departure of his family, when Rick developed the portal gun and began traversing reality.
Because the invention of portal travel occurred during his late thirties or early forties, and because the multiversal war consumed several decades before the Citadel reached equilibrium, the infinite versions of Rick inevitably converged on senior citizen status. Variants who died young never survived to join the collective, while infant or adolescent variants were functionally useless for Citadel operations. The universal consensus of a 70-year-old Rick is not a random biological coincidence. It is an artificial selection bias enforced by the Citadel's foundational architecture.
