By duration · Order from shortest to longest.

1. A single blink of the human eye 348 ms

   We blink around 15-20 times a minute, and the brain edits out the darkness — you're effectively blind for about 10% of your waking hours.

2. One human heartbeat at rest 798 ms

   Your heart beats roughly 100,000 times a day and around 3 billion times in a lifetime, pumping enough blood to fill an Olympic pool several times over.

3. A single round of professional boxing 3 min

   Round length was standardized by the 1867 Queensberry Rules, which also introduced gloves — before that, bare-knuckle rounds ended only with a knockdown.

4. The Apollo 11 mission, launch to splashdown 8.1 days

   Of the whole voyage, Armstrong and Aldrin spent barely 22 hours on the lunar surface — and only about two and a half walking on it.

5. An African elephant's pregnancy 1.8 years

   The longest gestation of any land mammal produces a 100 kg calf that can walk within hours — and is looked after by the whole herd.

6. The time since Vesuvius buried Pompeii 1.9K years

   The AD 79 ash preserved loaves of bread still sitting in ovens — one carbonized loaf even bears its baker's stamp.
