He was having brain issues ... serious ones. He had a traumatic brain test & he was in the bottom 10 percent & the docs told him his brain would stop functioning in 5 - 10 years. There’s a book called “Working Ourselves to Death” (1992) that goes into how physically, with extreme stress, you can work yourself into a spiral that can result in death. With extreme stress & overwork, you get into adrenal fatigue & evidently that brought on his autoimmune issues.
He went to a brain rehab center in TX & after that (plus finding out about the auto immune problem, etc.), I thought I heard him say he had another scan/test & his brain was looking ok, function was back to normal or close to it. I thought he was doing much better overall, although I know he really suffers with peripheral neuropathy - a close family member has it so I know how bad it can be.
I think he’s back on the stress wheel again with the state of the country, his views as to what needs to happen (unity, return to God, etc.) and it’s eating him up. He’s been very tired with a lot of travel. He had to take a month off to rest his vocal cords ... all signs he’s doing too much again, IMO. Anyway, I hope he can find some sort of happy medium & peace - he has a nice family & they need him.
Maybe Glenn should take a year (or two) off, then, to rehab/recuperate and focus on his family.
