*Slightly* off topic, but this is the global trend here on this wall, so please allow me to express myself:

1. Aging is nothing but degradation of our DNA information via replication of our cells. We happen to age every single second, mind you. When the DNA chain reaches the end, due to the disability of our mechanism to reproduce its cells without errors, we have the telomerase that is nothing more than Poly-A chains to eliminate the duplication errors. During our lifespan, those chains are getting shorter and shorter while the duplication reproduces more "errors" due to lack of them.

TL;DR: More Telomerase = More life.

2. What is life? What is the difference from your life and mine for example? The answer is simple. It's our memories. Memories are stored into our brains via biologic synapses which (in essence) are not very good way to store information. But this is what we got. I presume it won't be hard for next gen (quantum? ) computers to be able to "store" the memories of a person inside their "hard drive". The tech is already here - we now know what our brainwaves look like when we ie: move our hands, that's how scientists are able to produce bionic legs and hands and the person who "wears" them is able to control them via their brains.

3. Evolution NEEDS immortality (or if you prefer infinite lifespan). It's the way that we humans can evolve to better beings and develop our "next" versions. This is feasible right now (in theory) via several ways. I'd say we're in infancy regarding the tech we need to "make it happen" but "we know it's there".

Question is: Will we be here to see it happen? Or some redneck will "press the button" and "restart" the engine? It would be so pity.
