Exactly. Limiting Objects which can be described to physical ones
greatly limits what can be stated. Along with mental constructs (such as
rules, accounts, and conceptual works), situations (which can be sub-
divided into static situations and events) need to be modeled. (02)
Physical objects have spatio-temporal properties as well as mass. Mental
constructs have temporal properties, but neither spatial nor mass.
Situations have temporal properties and physical situations have physical
objects as physical participants. [Non-physical situations have only
non-physical participants, such as the static situation of a sick leave
account having 15 days in it or the event of a law expiring.] (03)

An illness is a physical event. A "form of illness" is a subclass of
Illness, which is a subclass of Physical Event. Both the organism that
is sick and the illness are spatio-temporal things, and thus have a
location, starting time, and ending times (as well as other properties
of spatio-temporal things). The organism is also a physical object, and
thus has mass (as well as other properties of physical objects). The
illness is also an event and thus has a doer and an object acted on (as
well as other properties of events). (05)

I agree. (07)
