Ok I will add to that - they seem to be going after the Metabolic Trap, they said the yeast do not grow ( become in a sort of cryogenic suspended state ? ) how do we know that in a human that wouldn't simply cause instant death ? maybe human has some way around that, a backup mechanism they don't know about. Also even if it does just make you tired, a human is not a yeast sat on a dish that can't change its environment, humans can change so many variables that might break the metabolic trap e.g. eating various things, exercise, temperature changes, infections, various drugs, rest, etc. If the metabolic trap provides a stable state where almost no energy is created, why do me/cfs patients experience a lot of change in their activity capabilities over time ?
