Procrastination
In terms of velocity, procrastination achieves a remarkable theoretical speed of zero. However, researchers at the Institute of Kinetic Avoidance argue this measurement fails to capture the phenomenon's true nature. Procrastination moves through time with perfect efficiency, consuming hours whilst producing no measurable output. This temporal velocity, measured in wasted hours per intention, can reach staggering figures of 47 hours per single uncompleted task.
Jet Ski
The modern jet ski achieves speeds of 65-80 kilometres per hour, with competition models exceeding 130 km/h. The Hydrodynamic Leisure Institute notes this represents approximately 40,000% more physical velocity than procrastination. However, the jet ski can only maintain this speed for the duration of its fuel supply, typically 2-3 hours. Procrastination, by contrast, can sustain its temporal consumption indefinitely, often spanning decades on particularly ambitious projects.
