There are a number of environmental stressors that subvert your "redox potential" which is essentially the quality of the charge potential across your mitochondrial membrane. This impacts many many things about the body as a whole -- the ability to generate energy to meet the needs of the cells/tissues, the ability to deflect toxic insults (think of it like having a mansion in the middle of a high crime hood, the high crime doesn't matter if your walls and security are top notch. If your walls have gaps and holes, then the toxins are a big issue).

So whatever drops that redox potential, will result in you being more susceptible to these high frequency high powered ambient EMFs. That's why it doesn't impact everyone the same. Redox potential is an n=1 situation. But generally living in modern high tech metro areas now is no longer a viable option for humans who want to maintain brain, heart function and not elevate risk of longer term chronic issues.

So yeah if you combine the mRNA insult in your body with living in downtown Portland or SF with 24/7 5G small cell towers beaming all around with no protections in place, expect anything from immuno disregulation to cancer risk to mood disorders to brain function diminishment (psychotic liberal mentalities in metro cities make more sense now?) to cardiac issues to happen. It all may start with something irritating but not life threatening, like migraines, poor sleep, lack of energy, etc. But those are just red flags and train stops on the way to worse outcomes.
