Below are my answers to some of the questions I've received. I'll be posting more on an ongoing basis.
I answer questions free through my twice-monthly newsletter Health, Home & Habitat. If you have a question you would like to submit, please send me an email with your question. It may take two to four weeks or longer for your question to appear in the newsletter. Usually I send an immediate quick answer to email questions, but then give a more detailed answer in the newsletter.
