  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. A dentist-approved tooth brushing session 2 min

    Studies show most people actually brush for about 45 seconds while believing they've done the full recommended time.

  3. A football (soccer) match, regulation time 90 min

    The ball is typically in play for barely 55 of those minutes — which is why competitions now add increasingly enormous stoppage time.

  4. Lent, from Ash Wednesday to Holy Saturday 46 days

    It's famously a 40-day fast, but the calendar span is 46 days — Sundays are feast days and traditionally don't count.

  5. The Romanov dynasty's rule over Russia 304 years

    It began with a 16-year-old reluctantly accepting the throne in 1613 and ended 304 years later with Nicholas II's abdication in 1917.

  6. The time since Vesuvius buried Pompeii 1.9K years
