Clearly a problem. Solved in Elephants and Sharks by having
ever-reproducing teeth (actually in elephants the process fails
after 10-20 "generations" and it is a major cause of elphant death).

Related to this is starvation among the "oldest-old" in western
civilizations where they can eat food (dentures work after-all),
but are unable to digest it effectively. IMO, more than likely
due to telomere loss slowing the replication of cells in the
stomach and small intestine leading to the accumulation of cells
that are rather dysfunctional with regard to nutrient absorption.

Spike, Spike, Spike, you just gotta get a script writer. This has
the same tragico-comedic line of several other films situated in
Mexico, "Dawn of the Dead" and "Desperado". You have to produce
a picture of this someday. I'll offer to play the role of the
technocrat who thinks tecnology will solve all the problems, only
to discover that solving one set leads to the creation of another
leading me to retire to reflect on the circular nature of life
on a beach in Costa Rica.
