Why can’t you live for ever if you replace organs when they start to fail.
Your body counts on cell replacement. Cell replacement comes from cell division. Cell division counts on DNA replication.
The Short Answer
Your body counts on cell replacement. Cell replacement comes from cell division. Cell division counts on DNA replication. DNA has a finite number of replications, enforced by chipping away at a terminator called telomere. When the telomere gets too short, the DNA can't replicate any more. This flags things in the cell that say Time's up, time to give it up, and the cell commits biochemical suicide. When we get very old, a lot of our cells have short telomeres. So the trick isn't organ replacement, it's telomere preservation.
