    Look, the maximum accomidation in diopters of people as they age
has been measured by instruments in many a study of aging people (the
Baltimore Longitudinal Aging Study being but the best one).  It doesn't
change linerally, but quite quickly, in the 40's.  I was merely
pointing out that the impression which most of us have of this process,
is in fact the correct one.  Terri can blather all she wants about this
or that might look to happen in the issue of visual accomodation loss
with aging.  I'm telling you what does happen.
