Procrastination
Procrastination demonstrates remarkable evolutionary persistence. Archaeological evidence from the Institute of Ancient Avoidance suggests humans were putting off cave paintings as early as 40,000 BCE. The phenomenon has survived every productivity revolution, from the industrial age to digital transformation.
The Cambridge Resilience Index rates procrastination's durability at 9.7 out of 10, noting that it actively strengthens when challenged by time-management seminars.
Swan
Swans possess impressive biological durability, with lifespans reaching 20-30 years in the wild. The Wetland Mortality Database notes they have survived ice ages, habitat loss, and the invention of bread (which, contrary to popular belief, causes them considerable digestive distress).
However, individual swan mortality remains inevitable, whereas procrastination appears functionally immortal—passing seamlessly between generations without genetic transmission.
