If you throw a frog into a pot of boiling water, he will jump out. But if you place a frog into a pot of cold water and and turn the heat on low, it will float there quite placidly. As the water gradually heats up, the frog will sink into a tranquil stupor, exactly like one of us in a hot tub, and before long, with a smile on its face, it will unresistingly allow itself to be boiled to death.
Now I'm not sure this really works with frogs, (I couldn't bring my self to find out), but I am certain that it works with people. I believe that we are all sitting in a big pot and the water is beginning to boil. Isn't it ?
