There are differences between the elderly, old age, those 65 years
and over, and so forth. Senescence is normal; senility is a disease. Growing
old is normal but aging is not, I am told by Dr. George Ehrlich, a promi-
nent physician who specializes in rheumatoid arthritis. Some colleagues
will have different opinions about these terms, but the biological-physio-
logical changes that occur in the life cycle are such that no one escapes
the certain damage to the brain cells, the skin tone, the wrinkling ravages
of time.
The gravity of time weighs on us all. We begin to age immediately after
birth. Brain cells deteriorate at some calculated rate of thousands per day.
The estimates of how many brain cells we have are very poor and very
varied: They range from 1010 in general to 1011 for the cortex alone. That
means 10 billion in the first estimate or 100 billion for the cortex alone.
No brain cells can be rejuvenated, unfortunately. How are these uncertain
data related to growing old? We lose brain cells every day. But we also
lose friends, income, relatives, property, and many other things as we grow
older.
This annual meeting was devoted to the measures we might take, so-
cially and politically, to protect the increasingly large number of older
people in our population. From 10 percent at 65 and over in 1975 to 20
percent in 2020, the country will experience significant changes. The older
population will become more important politically and may produce a ger-
ontocracy, not only in the United States but in the Soviet Union and other
countries as well.
The papers presented at this annual meeting are among the most articulate
and carefully stated articles we have had. I applaud the authors for their
cautious, succinct, and insightful comments and hope that our Academy
members will read this issue with special attention to the important topics
which Secretary of Health, Education, and Welfare, Joseph A. Califano,
Jr., who was our luncheon speaker, brought before us as a major set of
questions for public policy.
