1. A single wingbeat of a honeybee 4.4 ms

   Bees beat their wings about 230 times per second — that frequency is exactly what produces their signature buzz.

2. 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.

3. NASA's Perseverance rover travelling from Earth to Mars 203 days

   The 480-million-km cruise ended with the 'seven minutes of terror' landing — and the rover carried a small helicopter, Ingenuity, strapped to its belly.

4. The Second World War 6 years

   From the invasion of Poland to Japan's surrender, it remains history's deadliest conflict — fighting officially ended on a battleship in Tokyo Bay.

5. The construction of the Great Pyramid of Giza 20 years

   Herodotus and modern estimates agree on roughly two decades — meaning workers placed a multi-tonne block about every five minutes of daylight.

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.
