Thank you all for the welcome.
I have always had an interest in engineering. I went to sea as a Radio Operator at 18. I went to Iceland on a trawler in 1968. It was an adventure for a middle class boy from Preston who had never been away from home and never heard a swear word. I have had a life of adventure since that time. Travelling the world, having several careers, had lunch with a king, seen butterflies bigger than both of my hands, a polar bear swimming in the sea a hundred miles from anywhere and worked as a village Blacksmith. For the last 20 years of my life I had a successful career in computer programming after teaching myself when I was unemployed in the early nineties.
I would like to do it all again without the bad bits…….
