By duration · Order from shortest to longest.

1. A lightning flash from start to finish 198 ms

   What looks like one bolt is usually several return strokes in a row, heating the air to around 30,000°C — five times hotter than the Sun's surface.

2. 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.

3. A main-stage TED talk at its maximum allowed length 18 min

   TED's curator calls it 'long enough to be serious, short enough to hold attention' — even Bill Gates and presidents get cut off at the limit.

4. The Islamic holy month of Ramadan 29.5 days

   Because it follows the lunar calendar, Ramadan drifts about 11 days earlier each year — cycling through every season over 33 years.

5. The Berlin Wall standing, from construction to fall 28.2 years

   Since 2018, the Wall has been down longer than it ever stood — and more of it now sits in museums worldwide than in Berlin.

6. The time since Neanderthals went extinct 39.9K years

   They never fully vanished: most people outside Africa carry around 2% Neanderthal DNA, influencing skin, immunity, and even sleep patterns.
