Title: Twenty-plus years reveal their charlatanry
Review: This book has become more of a historical curiosity than a relevant guide to improving one's health. Although Durk and Sandy tried to do a morally defensible thing, their efforts to intervene into their aging processes via concentrated man-made chemicals don't seem to have succeeded. If you search for recent photos of them on the Web, you'll notice that these days they look like hell.
