How right you are, Radial! My dad is 83. He had a gas station when I was really young, drove stock cars, and has been a gearhead all his life. He's gotten me out of numerous mechanical situations, too. And I've rescued him a few times, too.
I hope my son feels the same way. He's a big shot computer applications guy at a major financial management company, but not overly mechanically inclined. Last weekend he said his washer was dumping bleach on the floor, and within two minutes, we had it fixed. It was crud in the filler tube. I knew what to look for from experience with my washer. It feels good to be able to help like that.
