A Grandmother, a Granddaughter, and Two Different Clocks Under One Roof

LAGOS — In the Adebayo flat above a busy market street, two women share a kitchen and disagree, gently, about what time it is. The grandmother, seventy-four and unenhanced, keeps the body's old clock: she tires by nine, wakes with the muezzin, needs her afternoon hour. Her granddaughter, nineteen and cognitively augmented since school, runs on the other kind — four hours of sleep, a mind that does not fog, a metabolism recalibrated to a tempo her grandmother's generation would have called inhuman and hers calls Tuesday. Neither designed this. They simply live it: two schedules braided through one household, the young woman padding in at dawn from a night's study to find her grandmother already making tea. The enhancement gap, so often argued in legislatures as a matter of caste and fairness, is here just a matter of overlap — the shrinking hours the two of them are awake and unhurried at the same time. "I don't envy her the clock," the grandmother said, pouring two cups anyway. "I only wish it kept better time with mine." They drink the tea in the one hour that still belongs to both of them.
