Procrastination
Procrastination operates on what the Cambridge Institute of Delayed Gratification terms 'inverse velocity'βthe faster a deadline approaches, the slower one moves toward completing the task. Studies indicate that procrastination achieves speeds of approximately negative 47 kilometres per hour relative to productivity benchmarks, effectively moving backwards through time whilst remaining stationary.
The phenomenon accelerates dramatically in the presence of Netflix, reaching what scientists call 'terminal avoidance velocity'.
Airplane
The modern commercial airplane cruises at approximately 900 kilometres per hour, a speed that would have seemed impossible to our ancestors and still seems improbable to anyone currently stuck in economy class. The Boeing 747 can transport 400 passengers from London to New York in seven hours, assuming nobody has forgotten their passport at home.
However, when accounting for check-in, security, boarding, and the inevitable delay, actual travel speed drops to roughly walking pace with extra steps.
