Will, would I utilize the five depth method for chronic or degenerative disease patients? 

Once I've located the empty position and depth, eg. ST position at the LU/HT depth, should I choose ST41 since it's the fire/mother pt. on the earth channel?

I have seen patients crave the specific foods/drugs/activities that defeat/disharmonize them when they are sick/imbalanced; why do people crave things that weaken them when they are sick/imbalanced?

Thanks, Aaron
