Dear Viewer, These videos date from 1999 or so. Most of what I say here is still true and relevant today, but as I look back at them now, I find minor errors and areas where we know somewhat more than we did back then. After recording these with our local PTTV crew, one professional videographer told me that for $10,000 for a half-hour take, she could bring these up to commercial broadcast quality. If you want to be our sponsor, call me! In the meantime, look at these as background information, a resource to help you formulate questions for your doctor. — Douwe Rienstra
