This is a MUCH better explanation: https://www.ncbi.nlm.nih.gov/pubmed/25459141

Killing off the misbehaving cells is an obvious solution but this must also shorten the organisms lifespan via organ failure.

You only get so many divisions from the zygote before a cell line must be killed off, put into senescence, or it starts malfunctioning due to accumulated mutations (~60). A good solution produces as many differentiated functional cells as possible while minimizing divisions from the zygote.

Really, this article shows a fundamental misunderstanding of how our bodies work.
