Steve: I must apologize for the delay in my response to on the subject above. Things have been just a little crazy around here lately. One of my sons just moved back home from California, and intensive marital counseling is ongoing. This has been a heavy burden for my family. My wife has had two stays in the hospital during the last two weeks (4 days each time) due to fainting (2 episodes), and a dizzy spell which is being called a "mini-stroke" or TIA (transient ischemic attack). The first is suspected to be related to high blood pressure and/or a need to modify her blood pressure medication. There is no apparent lingering effects from the TIA after the first 24 hours when her left side was affected. She is on a lot more medication now than she was before. For those on the list who would add these concerns to your prayer list my son's name is Jonathan, his wife is Christina, and my wife's name is Billie. Please be patient. I have done some work towards a response, and will do more as time allows. This is a subject which has both interested and affected me for almost 20 years. Soli Deo Gloria, John T. "Jack" Jeffery
