Children seek to learn from their parents and do so the best by age 5.
Adults? They don't normally make a change until they are near dead or one of their friends died, then they may start to wake up and think maybe they had better change some habits.
The problem all herbalist have always had: People in general don't try herbs until their MD has gave them the death sentance. The very few, who believe in Prevention are the Ones every herbalist desires to know. This is why I called the schooling; The School of Self-Applied Prevention. Everyone can do self-applied prevention, but the near dead people seeking for a herb to save their life will need professional aid 24/7 if they are to survive a lifetime of bad habits. Sadly the Amish Healer is the only such person I know of today that takes in such people and this is why he moved to a mountain top, because they will find him no matter where he goes! He is now taking my theory of educating others to reduce his work load.
