It is living, shown by the fact that it needs only nutrition and a friendly environment in order to grow and change.

Quite true. Also note that a 5 year old needs these same things in order to grow and change.

And the point of "viability" is just a measurement of the local technology since the point of "viability" is much different in a modern hospital than it is in a grass hut in Kenya.

Quite true. Also note that a 5 year old needs these same things in order to grow and change.

So do all adults.

It is really a mistake to refer to adults as "grown ups" because people continue to grow new cells until death.

Even life support can not cause new cells to grow, it will only retard the decay of cells for a while.

If you put a dead body on life support it will, over time, break down and rot.
