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.

I am a particular fan of integrative exercise - that is, exercise that occurs in the course of doing some productive activity such as gardening, bicycling to work, doing home improvement projects and so on.

Any drug can be used successfully, no matter how bad it's reputation, and any drug can be abused, no matter how accepted it is. There are no good or bad rugs; there are only good and bad relationships with drugs.

In my view, prescribing antidepressant drugs is too often a quick and easy substitute for developing treatment plans that address the totality of health concerns and lifestyle factors that have an impact on wellness, including emotional wellness.

As any doctor can tell you, the most crucial step toward healing is having the right diagnosis. If the disease is precisely identified, a good resolution is far more likely. Conversely, a bad diagnosis usually means a bad outcome, no matter how skilled the physician.

Technology has a shadow side. It accounts for real progress in medicine, but has also hurt it in many ways, making it more impersonal, expensive and dangerous. The false belief that a safety net of sophisticated drugs and machines stretches below us, permitting risky or lazy lifestyle choices, has undermined our spirit of self-reliance.

Human beings and plants have co-evolved for millions of years, so it makes perfect sense that our complex bodies would be adapted to absorb needed, beneficial compounds from complex plants and ignore the rest.
