Monday
Monday's power manifests exclusively through psychological channels, generating no motive force whatsoever. The day cannot pull a plough, carry a rider, or relocate so much as a pencil across a desktop. Its influence operates entirely within human neural architecture, where it achieves remarkable effects including reduced productivity, elevated absence rates, and measurable cardiovascular stress responses.
This categorical limitation proves significant when assessing practical capability. Monday cannot construct anything, transport anything, or accomplish any task requiring physical force. Its power remains conceptual rather than mechanical, exercised through human belief systems rather than biological or technological systems. The day's influence, whilst substantial, produces no work output measurable in foot-pounds or joules.
Horse
The horse generates 15 horsepower of sustained mechanical output, a figure so definitive that James Watt selected equine capability as the reference standard for all subsequent power measurement. Draft breeds including Clydesdales and Percherons routinely pull loads exceeding 8,000 pounds. Thoroughbreds achieve gallop speeds of 70 kilometres per hour whilst carrying riders through purely muscular propulsion.
This power output built civilisations. Horses ploughed the fields that produced agricultural surpluses enabling urban development. They carried armies across continents, pulled the wagons that settled frontiers, and powered industrial processes before petroleum alternatives emerged. Six thousand years of documented service demonstrate practical capability that no temporal concept can match.
