I respect that you have a different opinion on that.
You bring up something that I've been meaning to bring up though. I think the adrenals are like the heart, no matter how much physical excursion you put out, the heart muscle keeps going, unless you dangerously deplete yourself of electrolytes or have a building artery blockage, but that's not the heart's fault. At least I don't think the heart muscle gives out, but you get my point even if it can from stress.
I think that adrenals have to be physically damaged by a tumor or an infection to give out. The heart doesn't get cancer, but I think an infection can damage the heart.
