Dr. Joseph Mercola interviews Kristin Comella. Interesting facts: We would only live an hour if it weren't for our stem cells. The best source of stem cells is our own body fat. You can have a small amount of fat extracted and receive a large number of stem-cell treatments from this source -- at regular intervals, as you become injured or develop health issues. Stem cells know exactly how to help regenerate tissues, without any manipulation by "medicine." People who eat healthy have the best body fat for stem-cell growth; smokers have the worst. This is a fascinating interview, and most of the therapies discussed in it do not involve the use of embryonic stem cells (from babies), but adult stem cells that are extracted, stored and administered for personal use.
