I have found that my vocal chords and my throat are like a canary in a cave. If they don't feel right, a cold, flu or other general cootie is generally right around the corner. Does this send panic through me as I set out to sing or act? Yes it does. Does the same issue hold true for public speaking? Yes it does.
Many go from one diet center to another, or read diet book after diet book, looking for the easy, shed pounds quickly approach.

While it sounds easy, and may work short-term, the only way to true weight management is to put on your snow boots and stomp on the obstacles.
