Question: Is immortality possible?

Sebastian Gornik answered on 17 Nov 2016:

Theoretically “yes”. But in reality it is a very very unlikely scenario.

I actually work with an animal that is considered immortal, but only because it can make copies of itself without having to have sex and offspring, it can do this every once in a while and this way can basically always make younger copies of itself, although the single individual will die of old age its true copy, which is younger will live on, …

For humans however this is not a working strategy, we can only live for 100+ years and then we die because our cells and their DNA in them has accumulated to much errors.
