  The effort currently in vogue in some small circle of physicists to go from a
proton to nuclei to compact stars involves various aspects of particle and
nuclear physics that require input from laboratory experiments, transcending
narrow specialization in diverse sub-fields. Several topics on this matter are
discussed in this note. The notion of Cheshire Cat Principle is introduced for
nucleons, nuclei and dense hadronic matter and is confronted with experimental
data on the proton, two-nucleon systems and heavy-ion experiments, with a
leaping extrapolation to the structure of neutron stars. The matter discussed
here illustrates that a close contact with experiments, indispensable in the
present case, is essential for significant progress in {\it any} field of
physics. I suggest that this is a field that has a tremendous potential for
breakthrough in the Asia Pacific countries, particularly in Korea, where some
of the seminal works in this area have been done by young theorists, both pre-
and post-graduate.
