I certainly feel that the time is not far distant when a knowledge of the principles of diet will be an essential part of one's education. Then mankind will eat to live, be able to do better mental and physical work and disease will be less frequent.
I had many teachers that were great, positive role models and taught me to be a good person and stand up and be a good man. A lot of the principals they taught me still affect how I act sometimes and it's 30 years later.
It's easier to change what you do than people think it is. If you don't change, your field changes around you.
