If molecules were people, they’d all be in therapy, or receiving pills for hyperactivity.
No less an authority than a factoid on a Snapple bottle cap asserts that “at room temperature, the average air molecule travels at the speed of a rifle bullet.”
Physicists say we are being bombarded constantly by who knows how many bits and pieces of tiny “stuff” and don’t even feel it.
An occasional air molecule, that seems acceptable. But, really, do we have to know that mixed in with these are little pieces of Aunt Hilda’s ear wax that’s shaken loose, or stray chunks of milk that’s gone bad.
Ignorance really is bliss.
