Speaking as an old man in the 1960s, Sir Cedric Hardwicke said that his only regret was that he could not have lived in the Victorian Age—with penicillin. I am still grateful that I do not have to submit to the doctoring and dentistry of my childhood, yet I realize that advances in one field are interlocked with advances in all others. I could not have penicillin or modern anesthesia without aviation, electronics, mass communication, superhighways, and industrial agriculture—not to mention the atomic bomb and biological warfare.
