- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
