So a little from column A, a little from column B. Got it!

In all seriousness, I'm just interested in how much is being obscured when folk like Cox do a TV show, obviously written for those interested but not involved like myself. I've no idea what anything in your paragraph meant past the word "In" (yes, the first word), but I can definitely picture a loop, and get that there is a something which is transmitted / moves / traded / otherwise-not-at-its-origin within that loop, and trying to understand what that something is will leave me drooling into the carpet.

Still, I'm glad I asked. Thanks!
