Spare a(nother) penny? Or two?

Just one sentence from "The Age of Alzheimer's" by the Hon. Sandra Day O'Connor, Dr. Stanley Prusiner, and Dr. Ken Dychtwald, from the Op-Ed page of today's New York Times:

"As things stand today, for each penny the National Institutes of Health spends on Alzheimer’s research, we spend more than $3.50 on caring for people with the condition."
