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. A performance of Beethoven's Ninth Symphony 74 min

   Legend says the CD was designed to hold 74 minutes specifically so the Ninth would fit on a single disc — a Sony executive's favourite piece.

3. James Cameron's film 'Titanic' 3.2 h

   The movie runs longer than the actual sinking it depicts — the real ship went down faster than you can watch it go down.

4. An average swim across the English Channel 13.5 h

   Fewer people have swum the Channel than have climbed Everest — and rules forbid wetsuits, allowing only goggles, a cap, and grease.

5. The time since a human last stood on the Moon 53.4 years

   Gene Cernan traced his daughter's initials in the dust in December 1972 — no boots have touched the surface since.

6. The Ottoman Empire 622.7 years

   Founded before the printing press, it ended after the airplane — the empire spanned 623 years and three continents at its height.
