I guess this is one of those times that my ever advancing age benefits me. I remember when ordering something meant putting a stamp on an envelope that contained an actual paper order form, filled out with a pen, along with a handwritten check as payment. I expected to wait at least 2-3 weeks from the time the mail carrier picked it up at the house, until I received the product(s).

Sometimes I marvel at how much we've forgotten, or simply never knew existed in the first place.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
