Welcome to Day 27! For as long as I can remember, I have been very introspective, constantly considering how the world works, why certain things happen the way they do and in general, wondering about a lot of things. While this blog has been a look back at 35 years as a professional photographer, I am much more than what I do for a living and there are many topics I consider to be even more important than my life's work. Today, as I do from time to time, I'm talking about and asking questions about one of life's great mysteries. I hope you'll take it in stride and contemplate it for yourself.
