SanDisk sells very pretty expensive plastic bricks that excel at disappointment and confusion (like when a USB flash drive decides to become permanently read-only).
Recent findings involve research with the endoplasmic reticulum that appears to go off the rails when over-stressed breaking the mitochondria within a cell robbing it of ATP production and increasing lactate (related to metabolic acidosis) in the body:
My current reasoning is somehow to recover you've got to pace yourself just enough to encourage new mitochondria to form, but
not so much that you experience PEM/crashing. The ME/CFS people have been discussing pacing for years. So:
Fail With
staying in bed for weeks doing as little as possible (a very slow success?-- mitochondria aren't encouraged to form)
trying to train it away with exercise/exertion (a quick fail-- the stressed ER will break mitochondria and flood body with lactate and set you back with a slew of acidosis-caused symptoms that will take time for the body to resolve. e.g. kidneys excreting the acid, COVID diabetes from gluconeogensis of lactate into glucose in order to raise the body's pH away from acidosis)
