In the last experiments a three CA system differentiated and blossomed. Finally two CA died and only one continued living. Here we demonstrate that by diverting more resources (age) to the declining CA, at least one can be rescued. Below are three CA and their age structures. CA-2[mean age] sets max age of CA-1. CA-3 diverts its age increment to CA-1
The graphs depict maximal ages of the three CA. Between them is the oscillating CA-2 [mean age] CA-3 (green) donates its age increment to CA-1 whose age rises, while CA-3 age declines until CA-3 dies
In the following experiment CA-2 donated its age increment to CA-3, and its aging velocity = 0. Consequently CA-3 aging declined less steeply. Upon CA-1 death, CA-2, and CA-3 stopped transferring their age increments to CA-1 and their ages started rising. CA-3 was rescued.
In both experiments CA-2 did not differentiate, and its cells did not die. CA-2 is an undifferentiated stem process, which maintains the system, otherwise it would die. Stem process may donate its age increment to other processes, however its age never drops below one.
