I think believing technology to be the only way for a human to be immortal is quite a foolish thing. There are many possible ways, both accidental, and/or intentional through experimentation, that humans of the past could have become immortal. I am of this opinion for reasons I will not say. Some I'm sure are alive today. Though, I don't want to get into my reasons for believing this.
Obviously know a days, more and more people are striving for it, with the existence of the internet, religious skepticism, exchange of information, etc. I bet without a doubt several current millionaires & billionaires have privately funded research labs performing likely inhumane, unethical, and illegal experiments, to try to discover, some form of immortality. If some billionaire funded a private lab and discovered it, do you think they would share it? I don't think so. At least, I wouldn't.
I personally don't believe physical immortality to be all that big of a milestone. It is merely one more step in the constant battle for self-preservation. The real question is, whats next.
I want to hear what you guys think. Yes, No? Your thoughts on the matter, or any additional thoughts?
