Monday
Monday demonstrates supernatural stamina through its unfailing weekly recurrence. For approximately 52 iterations annually, Monday arrives without fail, deviation, or mercy. This represents a stamina unmatched by any athletic endeavour, corporate initiative, or human relationship.
The day has maintained its schedule since the standardisation of the seven-day week, a stamina spanning millennia of continuous operation. No pandemic, war, economic collapse, or social upheaval has ever cancelled, postponed, or rescheduled a Monday. Even when humanity retreated indoors during global lockdowns, Monday continued arriving with characteristic punctual indifference.
Monday's stamina extends beyond mere persistence to encompass psychological endurance—the day never tires of generating dismay, never loses enthusiasm for disrupting weekend contentment.
Tennis
Tennis matches can extend to extraordinary durations, with the historic 2010 Wimbledon encounter between Isner and Mahut lasting eleven hours and five minutes across three days. This represents Tennis at its most stamina-intensive, pushing human endurance to televised limits.
Standard professional matches, however, typically conclude within two hours, and amateur games rarely exceed the patience threshold of participants before someone suggests retiring to the clubhouse. Tennis equipment demonstrates notably poor stamina, with strings requiring regular replacement and tennis balls losing bounce with concerning rapidity.
The sport's seasonal calendar, whilst extensive, includes rest periods and off-seasons that Monday would find contemptibly indulgent.
