Hi, my name is Tom Chao. Here's a little about myself. I have been retired for several years now. Before that, I worked as an electronics engineer at an U. S. Navy research and development facility for 34 years. I have two sons, one is a software engineer, and the other a chief surgery resident. My wife and I live in Connecticut. My hobby is collecting paper money from different countries of the world. I like to surf on the net, and work on my web page.
