      We measured and counted a lot of things when I was a medical student and resident that no longer seem to matter. What we measured and counted with the tools that were available seemed vitally important then and reflected our contemporary understanding of cardiac pathophysiology. Just 30 years later, the tools and the concepts seem very primitive. The story of the evolution of scientific paradigms has been written many times, as have the follies of overenthusiastically embracing unproved observations. I would like to arrive at a similar destination, but by a different and less chronicled route, focusing primarily on measurement tools and the beliefs they reinforced, with a few humble examples.
