Ah, I see. Context is everything. I have not grown HeLa cells, but they are a great example of how a tissue can be taken from a living (or dead) person and maintained indefinitely as long as it is provided basic survival needs, i.e., food, oxygen, warmth, and CO2. But, no matter how long those cells are maintained and continue to live, the continued survival of the tissue is completely independent of the survival of the person. In Jahi's case, the cells were not removed from her body, but are cultured within the body through ventilation, externally supplied heat sources, and nutrient solutions inserted through an IV. The fact that the cells are kept alive does not mean that Jahi is alive, because that person died back in December, 2013.
You are actually doubling down in your inane analogy?
I also recommend a refresher course in cell culture and in basic A&P to address your difficulty in understanding the difference between cells and tissue.
Look, you keep avoiding the issue which is it has been two years and by now according to you and others her body ought to have fully rotted away.
You were wrong.
