"Whether the adrenals can actually fatigue or not is the question, which I believe is your argument, correct?"
Yes and I personally believe now that they can not fatigue.
"I believe, whether they are fatigued or not, they lose some ability to keep up with the demand placed on them."
Here's what I asked in your thread and I think your answer would be yes:
Have any of you thought that maybe the adrenal glands just don't have the capacity to produce enough hormones is times of prolonged extreme stress rather than they "gas out"? They are rather small little glands. I'm much more open to that, but it would still mean nothing is wrong with them.
