The interesting thing is that many folks in fact actually have CRC - and have NO clue they have it. Most docs haven't a clue, and many patients with CRC in fact have become the walking wounded, living haf-lives.
The many severe physically and psychologically stressed folks without CRC perhaps did not have Antibiotics , the Pill, cortocosteroids or were influenced by factors (the causes, etc) which increased their susceptibiliy. I'll bet if these guys did that many WOULD in fact develop CRC in time.
You are correct, there are certainly many candida sufferers who have less stress, but having candida (or any infection) unfortunately for that matter IS a stress on the body in it's own right. I have learned that "stress" is essentially ANY deviation from the body's physiological/psychological and emotional "norm", if there was ever a way we could define the "norm".
