By duration · Order from shortest to longest.

1. The Wright brothers' first powered flight 12 sec

   The 1903 flight covered just 36.5 metres — shorter than the wingspan of a Boeing 747. Within 66 years, humans were on the Moon.

2. A proper hand wash, by WHO guidelines 19.8 sec

   The recommended scrub lasts about as long as singing 'Happy Birthday' twice — most people manage barely a third of it.

3. A typical national anthem performance at a sports event 1.5 min

   Uruguay's full anthem runs about five minutes, while Japan's 'Kimigayo' has just four lines — the shortest lyrics of any anthem on Earth.

4. A horse's pregnancy 340 days

   Foals can stand within an hour of birth and gallop within a day — a survival feature for a prey animal born on open grassland.

5. The Siege of Leningrad in World War II 2.4 years

   Through the blockade, scientists at the city's seed bank starved to death rather than eat their collection of edible seeds and potatoes.

6. How long the Parthenon has been standing 2.5K years

   It survived largely intact for over 2,000 years — until 1687, when a Venetian shell hit the gunpowder the Ottomans had stored inside.
