".05" is a bullshit number, anyway.
They hafta cheat on the number, cause nobody'd believe the *real" number they're measurin.
One machine, set whatever way it is.
An "average" person, of "average" sex, with "average" lung capacity, blows an "average" amount of air from the "middle" of their alveoli.
Their lungs gotta be "average", or the results won't be "right".
Through possible mouth alcohol, or blood alcohol from a cut lip, bit tongue, or bad gums.
And the claim is they can measure blood content with accuracy in the ten thousandths, 1/10,000 range, not from blood, but from air in the lungs.
Anybody old enough ta drink, should be too old to believe that fairy tale.
Lol...aren't you ever concerned that some kid might read the stuff you write and believe it?
