Short Answer. Your Health.
In the beginning, that being within the last fifty years, it was fairly safe to consider living a life thinking about our health when it came to what we ate. That has changed dramatically. In the last fifty years we have destroyed our food system and installed a very suspect alternative. Somber? No. We finally have to pay attention to our health. Sounds to me like something that should be part of our daily life. Being good to ourselves and those around us.
If you are not on this journey, I hope you will join in, together we have influence.
