Monday
Monday's stamina presents a paradoxical temporal phenomenon. While technically constrained to twenty-four hours like all other days, Monday exhibits a peculiar property that scientists have termed 'subjective temporal dilation.' Laboratory studies confirm that Monday appears to last approximately 1.4 times longer than equivalent periods measured on Fridays.
Furthermore, Monday demonstrates remarkable regenerative capabilities. No matter how thoroughly one survives a Monday, another emerges precisely one week later, fully restored and equally relentless. This weekly resurrection cycle has continued uninterrupted since the Babylonians first codified the seven-day week, representing roughly 261,000 consecutive appearances over five millennia.
Boxing
Professional boxing matches demand extraordinary cardiovascular endurance. Championship bouts extending to twelve three-minute rounds, with one-minute intervals, total forty-seven minutes of intense physical exertion. Fighters maintain heart rates exceeding 180 beats per minute while simultaneously defending against and delivering powerful strikes.
However, boxing's stamina operates within finite boundaries. Even the longest matches conclude. Recovery periods between fights span weeks or months. The human body imposes biological limits that Monday simply ignores. A boxer might compete forty times in a career; Monday arrives fifty-two times annually regardless of physical preparation.
