Each cell in our body is derived from a cell that existed 3 billion years ago. It seems twisted argument that some how cell in an individual body must die but can renerate for billions of years if it only met with other damaged cell. There are fair amount of examples such as a-sexual bacterial reproduction where cell essentially survives for ever. There are many species known to live on for multiple of 100 years.
