I hate math, even with a calculator. I'm serious when I say I'm more a slide rule guy. In fact, my wife has been grinding on me to get a smart phone. She is lucky I have a cell phone. In fact, when we met I didn't have a cell phone. I only got one when we became engaged. And when this old flip phone I has goes to the big phone garbage dump in the sky, I'll never get another one. I'll be back to land line only.
