By duration · Order from shortest to longest.

1. 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.

2. 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.

3. Charles Lindbergh's solo flight from New York to Paris 33.5 h

   Lindbergh went without sleep so long he reported hallucinating ghostly figures in the cockpit somewhere over the Atlantic.

4. 'Logistics', the longest film ever made 35.7 days

   The Swedish experimental film follows a pedometer's supply chain in reverse, in real time, from a Stockholm shop back to a Chinese factory.

5. New Horizons' journey from Earth to Pluto 9.5 years

   It left Earth as the fastest spacecraft ever launched — and Pluto was demoted from planet status just seven months into the trip.

6. The age of the oldest known figurative cave painting (Sulawesi) 51.1K years

   The Indonesian rock art depicts wild pigs and human-like figures — painted tens of thousands of years before Lascaux's famous bulls.
