By duration · Order from shortest to longest.

  1. A single sneeze, from sharp inhale to achoo 1.5 sec

    A sneeze can launch droplets several metres, and you can't sneeze with your eyes open without effort — the blink is part of the reflex.

  2. An average human yawn 6 sec

    Yawns are so contagious they jump species: dogs catch yawns from their owners, and even reading the word can trigger one. You're welcome.

  3. A standard university lecture 50 min

    Attention research suggests student focus starts lapsing after 10-15 minutes — which is roughly when most lecturers are just warming up.

  4. The world's longest scheduled flight, Singapore to New York 19 h

    The route covers about 15,300 km. The aircraft is configured with no economy class at all — partly so passengers survive the experience.

  5. One year on Mercury (a full orbit of the Sun) 88 days

    Mercury's spin is so slow that a single sunrise-to-sunrise day there lasts about two of its years — you could outwalk its sunset.

  6. The Republic of Venice 1.1K years

    The 1,100-year republic elected 120 doges using a bizarre multi-round lottery system specifically designed to prevent vote-rigging.
