Ralph Waldo Emerson

I was a keen observer and listener. I picked up on clues. I figured things out logically, and I enjoyed puzzles. I loved the clear, focused feeling that came when I concentrated on solving a problem and everything else faded out.

I turned 65 last year, and each year I get more and more interested in human health. For most people it happens around age 50, but I've always been a slow learner. It's critical in terms of the cost of health care.
