You can't afford to get sick and you can't depend on the present health care system to keep you well. It's up to you to protect and maintain your body's innate capacity for health and healing by making the right choices in how you live.
You just kind of have faith. If that sounds kind of mystical it's because I really don't know how it works but I trust that it does. I try to write the way I read in order to find out what happens next.
