Wow, what a fantastic explanation. I never realized it, but I did think turbulence was unlimited and could just get worse and worse to infinity. So, when it started, I would get a mental image of it just getting more and more intense until the plane was tossed around helplessly.
But after listening to Keith's CD's, I realized I was thinking of turbulence entirely wrong. It's just a natural part of flying... just as a slight chop is a normal part of being on a boat. If I am experiencing turbulence, it is merely an indication I am flying somewhere... because I have chosen adventure and NOT to sit at home and let fear control my life.
