The glimpses of human strength and frailty that a physician sees are with me still.

First of all, many human diseases are influenced by, if not caused by mutations in genes.

People are not the only interesting organism on earth. From the point of view of scientific or commercial value, there are lots of interesting organisms.

And of course, identifying all human genes and proteins will have great medical significance.

As I look back on the last few decades of my life, I am struck by the good fortune that came my way.
