A personal note
§When I first got involved with computers in 1951 there were only a few hundred of us in the field.  Obtaining one of the first PhDs from Harvard in what was later called Computer Science, I continued to participate in the “information revolution”, making several key contributions over the years. 
§
§Today, we are in a very early stage of a “longevity revolution,” also of vast importance.  The current status of this new revolution reminds me of the computer revolution in 1955—the same excitement, rate of new ideas and discoveries, rate of new people coming into the field, new practical applications, intractable problems being cracked, and incredible promise for the future.
