People originally thought that death was an inevitable destiny that god decided when he created man. That was what Gilgamesh had learned when he went on a journey in search for immortality.
But fast forward to today, we see death as not what god has decreed, but as technical challenges that we have to overcome.
Interesting information about a project to use nanotech to develop a bionic immune system, suggesting that by 2050, we can see people that are a-mortal, meaning that barring from any fatal trauma, their lives could be extended indefinitely.
