One of the most obvious ways dogs can improve our physical and mental health is via daily walks.

• As an American, you have a right to good health care that is effective, accessible, and affordable, that serves you from infancy through old age, that allows you to go to practitioners and facilities of your choosing, and that offers a broad range of therapeutic options.
• Low levels of vitamin D in the population as a whole suggest that most people need to take a vitamin D supplement. This may be especially true for seniors, as the ability to synthesize vitamin D in the skin declines with age.
• Gardening is not trivial. If you believe that it is, closely examine why you feel that way. You may discover that this attitude has been forced upon you by mass media and the crass culture it creates and maintains. The fact is, gardening is just the opposite - it is, or should be, a central, basic expression of human life.
• A beautiful bouquet or a long-lasting flowering plant is a traditional gift for women, but I have recommended that both men and women keep fresh flowers in the home for their beauty, fragrance, and the lift they give our spirits.
• 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.
• We need to accept the seemingly obvious fact that a toxic environment can make people sick and that no amount of medical intervention can protect us. The health care community must become a powerful political lobby for environmental policy and legislation.
• Fear and greed are potent motivators. When both of these forces push in the same direction, virtually no human being can resist.
• Get people back into the kitchen and combat the trend toward processed food and fast food.
• Clearly, America's dysfunctional food culture must bear some of the blame for our excess pounds, but it's likely our walking-averse lifestyles contribute as well.
• Everyone prefers some foods over others, but some adults take this tendency to an extreme. These people tend to prefer the kinds of bland food they may have enjoyed as children - such as plain or buttered pasta, macaroni and cheese, cheese pizza, French fries and grilled cheese sandwiches - and to restrict their eating to just a few dishes.
