"You don't think that it is possible for those organs to 1) give out entirely or 2) produce at a sub-optimal level because they have been damaged from years of over-production ?"
I understand the logic and remember, I used to believe in "AF". I supposedly had "AF" for years, but every time I got my cortisol tested, it was either normal or elevated.
But here's my problem with the "AF" theory of over-use causing the adrenals to "gas out", wouldn't people with Cushing's disease eventually develop Addison's disease?
