Avogadro's constant is 6.022 x 10^23 [1]. There are a hundred billion sets of a trillion constituent particles in ever mol of anything. A reaction that happens to water once in a trillion years would occur 20,000 times a second for each 18 mL of water.

You're being an engineer :-) Yes, I am aware of those things but those sorts of numbers do not correspond to day-to-day usage and intuition of most people (as I said).
