I visited my mother this afternoon and she turned on the Oprah Winfrey Show partway into the program. Oprah and her guest, Dr. Mehmet Oz, were discussing colon health and elimination function. He had specimens of healthy and unhealthy colons. They went on to discuss some other health topics and he had some other specimens. It was quite interesting and informative. Dr. Oz and another guest on the show, Dr. Michael Roizen, have written a book titled “You: The Owner’s Manual”.
