I suspect it's worse than just having to ignore rest for work. I think it's our food supply. In the neverending effort to always squeeze maximum profit out of everything, we've made all of our available food terrible.

I've been fighting with chronic fatigue and pain for most of my adulthood. Only in the last year have I discovered how much better I feel when I avoid processed foods. That's an incredibly difficult thing to do in Western society, yet when I stick to eating only clean foods without garbage added to them, I actually feel okay. It's only gotten more pronounced as I've aged, and I'm now at a point where I can't ever eat anything that has corn, wheat, soy, etc.

Maybe in a more natural environment these foods wouldn't immediately inflame my body and mind, but since we eat so very much of the same starchy, fatty garbage every day, I believe my body has begun to revolt and won't tolerate any now.

Current medical thinking is that maybe 20-30% of the population has some sort of undetected food sensitivity to common food ingredients. That's a significant portion of people who feel bad all the time but don't know why.
