Procrastination
Procrastination demonstrates extraordinary resilience as a behavioural pattern. Despite centuries of productivity literature, motivational speeches, and time-management applications, the tendency to delay remains functionally undiminished in the human population. Researchers have documented procrastination in ancient Egyptian hieroglyphics and Greek philosophical texts, suggesting a lineage of at least four thousand years. No intervention, methodology, or technological solution has succeeded in eliminating this behaviour from the human repertoire.
The durability of procrastination appears to stem from its neurological foundations. The limbic system's preference for immediate reward consistently overrides the prefrontal cortex's capacity for long-term planning. This hardwired cognitive architecture ensures procrastination's perpetual presence regardless of external circumstances or earnest resolutions made at midnight before deadlines.
Great Wall of China
The Great Wall's durability presents itself in more tangible terms. Sections constructed during the Ming Dynasty (1368-1644) remain structurally sound, with some portions maintaining their original defensive capability half a millennium after completion. The wall has survived earthquakes, invasions, weathering, and the rather more recent threat of tourist erosion. Its physical presence endures whilst empires that built it have risen and fallen multiple times.
However, durability is not uniform across the structure. Approximately 30% of the Ming-era wall has deteriorated significantly, with some sections reduced to foundation stones. Earlier constructions from the Qin Dynasty have fared worse, with many stretches existing now only as subtle undulations in the landscape. The wall endures, but it does so through continuous decay and selective preservation.
