A member asked:

Why do we still die of organ failures? i thought modern medicine has all the machines that can replace organs. for example, dialysis for kidneys, no?

A doctor has provided 1 answer

No: Modern medicine is awesome but the human body is incredible. We can mimic the kidney with dialysis but we can't quite get it right. Eventually we fail. We have not been able to do it nearly as well as the body itself. Our body is actually programed for death through apoptosis, or death of the individual cells. The only cell that live forever are cancer cells.
