Q: Exactly why is it? What happens if it gets too acidic; too alkaline? Why does that happen? Where can I get more information about this online? Thanks!

A: http://www.snyderhealth.com/blood.htm is a webiste that can tell you a great deal about your Ph. Essentially, if you are too acidic, or too alkaline, your body will try to compensate for the imbalance, but eventually will decompensate. Too muc of either will affect all your systems and your organs, to the point of failure.
