24 years ago I got an audio cassette... I listened to it more than 10 times. It was titled "Dead Doctors Don't Lie"
I am following what I learned there about 90%... and I haven't been ill for about that long.
Here is a more recent talk by the same person, Joel Wallach. I also heard him live... Enjoy
Warning: it requires a little bit of intelligence... do you have it?
