I retired in July 2019 and I posted more before that as, being on call / standby a lot I had more time on my hands!

As to motives for posting. Where do I start? Why discuss anything with anyone? We all know we will change no-one's mind. Some may think they can make a valid point. Others may enjoy some feeling of false superiority. Some just like the cut and thrust. Why do you post, Rain Dog?
