MW: Hmm. Now I would say processes bring about change, rather than that
they are the change. We have something we call event that is the temporal
boundary of a new state. That is what marks the change, but the event is
caused by what we call an activity (where an activity may cause and be
composed of any number of events).

MW: More 3D speak. Me as a child and my childhood are the same thing.
My growing processes act on myself. Me as a child/my childhood are
part of me/my life.    (010)

MW: Then me as an adult is another part of me/my life (the same me/
my life).    (012)

> The whole process which is his life has (at least) these two parts.    (013)

MW: As I do (as a physical object).
