Procrastination
Procrastination predates written history and likely predates language itself. Archaeological evidence suggests early humans postponed essential survival tasks despite immediate environmental pressures, a tendency that defied natural selection yet persisted nonetheless. The phenomenon appears hardwired into human neurology, representing perhaps the most ancient cognitive pattern still actively shaping behaviour.
Ancient Greek philosophers documented the struggle against akrasia, the tendency to act against one's better judgement. Egyptian scrolls contain complaints about delayed projects. Roman writers lamented the universal human tendency toward tomorrow. Procrastination has survived every civilisation, every technological revolution, and every productivity methodology. It will almost certainly outlast any individual or institution currently in existence.

The medical profession traces its origins approximately 5,000 years to ancient Egyptian practitioners who first formalised diagnostic and therapeutic approaches. From Imhotep through Hippocrates through modern specialisation, the figure of the healer has maintained continuous presence across civilisational transitions.
The profession regenerates through educational institutions producing approximately 700,000 new physicians annually worldwide, ensuring continuity regardless of individual practitioner mortality. Medicine has survived religious persecution, plague, war, and the occasional poorly designed healthcare reform. Yet procrastination, being a feature of human consciousness rather than an institution, possesses a longevity advantage that organisational structures cannot match.
