I have argued for years that we do not have a health care system in America. We have a disease-management system - one that depends on ruinously expensive drugs and surgeries that treat health conditions after they manifest rather than giving our citizens simple diet, lifestyle and therapeutic tools to keep them healthy.

I believe that it may be normal, healthy, and even productive to experience mild to moderate depression from time to time as part of the variable emotional spectrum, either as an appropriate response to situations or as a way of turning inward and mentally chewing over problems to find solutions.

My passion for gardening may strike some as selfish, or merely an act of resignation in the face of overwhelming problems that beset the world. It is neither. I have found that each garden is just what Voltaire proposed in Candide: a microcosm of a just and beautiful society.

If you have difficulty sleeping or are not getting enough sleep or sleep of good quality, you need to learn the basics of sleep hygiene, make appropriate changes, and possibly consult a sleep expert.

The notion that a human being should be constantly happy is a uniquely modern, uniquely American, uniquely destructive idea.

I think instead [of happiness] we should be working for contentment... an inner sense of fulfillment that's relatively independent of external circumstances.
