Dear Josh:

Great to get your note and be caught up on your personal life, which looks
very attractive! I enclose a photo about 3 years old, some 2 years after my second
marriage to Dr. Ken Fremont-Smith (a physician; his dad was Frank of the Macy Foun-
fat ion- ). He has 4 grown sons, I have 2 grown daughters and a son.. None at

How to do particular research depends on available methods. All research
depends on some kind of model and assumptions. ( I must have misunderstood your
statement.). The problem at the level of complexity of development and aging is
to get and integrate sufficient data for a dynamic. model which is so ) compl ex and
realistic that it has predictive value. This is now possible.

I do not know and could not decipher (!) the last name of Nancy M--- at Yale. JO
Would you send her this other reprint?

Thanks and best regards,

Lu barn .
