Knowing that most new and unconventional ideas do not always find the warmest of receptions, I asked Dr. Katzman if he recalled the response of other scientists at the time. “Was it controversial? Oh, yes,” he said, laughing. “I mean, it was new, so automatically it was controversial. But I know I believed it then and I believe it now,” he added bluntly. “We had the data.”

As it happened, he also had something more. Katzman found that the Group A brains were not only somehow protected but also bigger. As he wrote at the time:

In regard to the number of large neurons in the three regions of the cortex measured, these nursing-home residents surpassed the subjects in the control group as well as the demented patients with Alzheimer’s disease . . . the brain weights in Group A were greater than in the other groups, suggesting that there has been less atrophy than normally found in the very elderly or that this group of patients started with more neurons and larger brains and thus had greater reserve.
