I just had some weird thoughts. Right now we have the technology, artifical hearts, limbs, etc. Recent news articles I've read about how the technology now on reading thoughts, already people can think of turning on tv, electrical things and it happening with a chip implanted. Things right now that are made for those with disability, paralysis, etc. How close are we to the point that most of the human body can be replaced by machine, preserving the brain, allowing on to escape aging?
Even read how science may be coming up with things to reverse aging. So other then being killed, physical trauma, it seems man is close to allowing one to physically keep existing.
