James Bond
Monday
Monday's existence predates recorded history. The seven-day week emerged from Babylonian astronomy approximately 4,000 years ago, and the designation of a first working day followed naturally. Monday has outlasted empires, religions, and countless cultural movements.
Unlike Bond, whose continuation requires active effort and investment, Monday requires only that humanity continue organising time into weeks. Given the deep structural embedding of this system, Monday's longevity appears essentially unlimited.
