HOW OLD ARE YOU REALLY? ABOUT THE FOUNTAIN OF YOUTH TESTS
The tests have proven to be accurate, simple and true in thousands of research hours, dozens of laboratories and hundreds of studies.
I have examined the research data for you and pulled out those tests that can be done quickly at home without any special equipment and
at little cost to you.
No one compiles data such as this alone, and I'm no exception. I had a lot of help from some very knowledgeable folks. Two wonderful
Canadian researchers wrote a book called Your Vitality Quotient (Warner Books, 1989). They were really the ones who got my own juices
flowing about my personal potential for youth and who first introduced me to the shock of determining my own true biological age. Once these
two innovative scientists got me started, there was no holding me back. Other tests were adapted from such books as Controlling Cholesterol
(Bantam Books, 1988) by Kenneth Cooper, M.D., and Biomarkers (Simon & Schuster, 1991) by William Evans, M.D. and Irwin Hosenberg, M.D.,
as well as many, many others. Go for it. Become your own biological detective. I guarantee you won't be disappointed and the journey will be the
most interesting one you will ever take.
