By duration · Order from shortest to longest.

1. One full rotation of the London Eye 30 min

   It moves so slowly — about 0.9 km/h — that it usually doesn't stop to let passengers on; you simply step into the moving capsule.

2. 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.

3. The average adult's actual night of sleep 6.8 h

   Smartphone-tracking studies put the global average well under the recommended eight hours — and humans sleep less than virtually any other primate.

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. One orbit of Pluto around the Sun 247.9 years

   Pluto hasn't completed a single orbit since its discovery in 1930 — it won't finish its first 'observed year' until 2178.
