I started a new sort of treatment — immunotherapy — last week. It is not without its hazards, but I hope it will give me a few more good months. But before beginning this, I wanted to have a little fun: a trip to North Carolina to see the wonderful lemur research center at Duke University. Lemurs are close to the ancestral stock from which all primates arose, and I am happy to think that one of my own ancestors, 50 million years ago, was a little tree-dwelling creature not so dissimilar to the lemurs of today. I love their leaping vitality, their inquisitive nature.
Next to the circle of lead on my table is the land of bismuth: naturally occurring bismuth from Australia; little limousine-shaped ingots of bismuth from a mine in Bolivia; bismuth slowly cooled from a melt to form beautiful iridescent crystals terraced like a Hopi village; and, in a nod to Euclid and the beauty of geometry, a cylinder and a sphere made of bismuth.
Bismuth is element 83. I do not think I will see my 83rd birthday, but I feel there is something hopeful, something encouraging, about having “83” around. Moreover, I have a soft spot for bismuth, a modest gray metal, often unregarded, ignored, even by metal lovers. My feeling as a doctor for the mistreated or marginalized extends into the inorganic world and finds a parallel in my feeling for bismuth.
