Senescence

From wikipedia:

Senescence (from Latinsenescere, meaning “to grow old,” from senex) or biological aging is the process of accumulative changes to molecular and cellular structure that disrupts metabolism with the passage of time, resulting in deterioration and eventually bringing about death. Senescence occurs both on the level of the whole organism (organismal senescence) as well as on the level of its individual cells (cellular senescence).

Naked Mole Rats have very long life-spans relative to their body mass, and to other small mammals, making them a highly interesting subject to study – they, along with humans, are outliers in longevity/body mass data. See chart here.

In terms of the objects – what is the senescence of the materials we are using? how will they change and deteriorate over time? which components will fail first?

The senescence of the materials in a work that is a channel for life from living creatures has an important conceptual role. Will the data feed out-live the materials? What happens when one of the NMR’s die? How is this indicated, does it need to be? What does death look like in this context (i.e. that of an artificial set of forms representing real-time life).
