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. The men's 100 m freestyle world record swim 46.4 sec

   Pan Zhanle's 46.40 at Paris 2024 stunned the field — he won by over a second, an eternity in a sprint event decided by fingernails.

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. The Woodstock music festival of 1969 2.8 days

   Billed as '3 days of peace & music', it overran badly — Jimi Hendrix closed at 9 am on Monday to a field mostly littered with sleeping bags.

5. The Holy Roman Empire, from Otto the Great to its dissolution 844 years

   Voltaire quipped it was 'neither holy, nor Roman, nor an empire' — yet it lasted 844 years before Napoleon finished it off in 1806.

6. The time humans have lived in Australia 65K years

   Aboriginal Australians' roughly 65,000 years make theirs the oldest continuous culture on Earth — some oral histories describe coastlines drowned by rising seas 10,000 years ago.
