Although I don’t doubt but that cortisol is a factor in some traditional heart attacks, what I have seen from the playing field situations and doctors referring to such suggests that adrenalin may be the tipping factor here.
And there is plenty of epidemiological evidence, such as from insurers, although regular autopsies and other study have been suppressed.
Exactly. There is no privacy in death, and cause of death is a public health matter (at least it ought to be).
You're not wrong referencing adrenalin. They negligently apply the label 'adrenal fatigue' to a condition they can't explain because there is wholly inadequate research on causation.
