I have a somewhat shy personality and find it difficult to strike up a conversation with strangers. I took early retirement on health grounds. I was a qualified electronics engineer and worked for the Marconi Company. Before that I had an amateur interest in electronics at the end of the thermionic valve era and the beginning of the discrete transistor days. Professionally most of my career was in the design of equipment using all types of logic from 74 series, 4000 series to ECL. Since retiring I have pursued my interest in woodworking. I have also spent a lot of time using the internet.
