Do you reckon that that the Hayflick Limit is applicable to this character? For those who do not know, the Hayflick Limit is roughly the number of times a cell can reproduce in its lifetime before it stops and breaks down upon programmed cell death. For normal cells in the body, this figure is roughly about 40-60 times.

For different specialist cells, this figure may be different. The only kind of cell I can think of that is not limited by this is cancer cells.

Also, is this character afffected by cellular ageing? Cellular ageing is generally defined as the progressive decline in the resistance to stress and other cellular damages, causing a gradual loss of cellular functions and resulting eventually in cell death. There are two types of cellular ageing: Exogenous factors that can lead to cellular damage include: http://www.patfyz.sk/ZapalWEB/node7.html
 * 1) Replicative ageing, which refers to the limited number of divisions that a single cell can attain.
 * 2) Chronological ageing, which is measured in time units by determining the mean and the maximum survival time of a post-mitotic yeast population and not of single cells.
 * mechanical (traumatic injury),
 * physical (extremely low or high temperature, ionising irradiation, microwaves),
 * chemical (caustic agents, poisons, venoms, genotoxic and proteotoxic compounds),
 * nutritive (deficiency of oxygen, vitamins and basic nutrients),
 * biological (viruses, microorganisms, protozoan and metazoan parasites).
