As most of you know science is a big part of my PB involvement. One interesting aspect is watching the changes in knowledge as it improves over time. What one study indicates as true often changes over the years as more facts are discovered. This has to be so because imperfect humans are involved in the process. By in large it is the human experience - we are not perfect so we must improve over time.

Merry Christmas and be assured that there are many , many questions left as unanswered so far on our collective journey.
