illy, don't take this the wrong way, because i'm not trying to insult you, and I could be wrong, but I've noticed a prevalent theme of you being someone that considers things based upon "the way things are", what is in your definition "natural", etc.
To put it simply, you think inside the box. Your perspective on life is brick-walled.
Myself and Jokerman do not think within confines and constructions of things that are completely understood. Just because something has always been one way, does not mean it SHOULD or WILL be that way. I don't see death as a natural thing or a barrier simply because that's how it currently works, I see death as a problem that can be solved for the greater benefit of humankind.
You aren't approaching this logically. When people have illnesses, we work to solve those illnesses. You wouldn't object to finding a way to cure cancer or AIDS or heart disease.
But if you take away so called "diseases" etc, why do people die? They say that people "die of old age" and they call it "natural death" - but age doesn't kill someone, and these deaths are far from natural.
People's bodies deteriorate over time due to many reasons, but don't get it twisted, these aren't things that can't be solved and you KNOW that already. I don't eat meat because it causes the human body to deteriorate faster. Eating meat causes acid buildup, which eats away at our internal organs. Meat begins to rot before the human body can digest it, leading to further problems. Animal fat clogs the arteries, reducing their ability to function. We know all these things.
Exposure to toxic chemicals in work environments causes deterioration of the human body, that's why we have health and safety legislation. The warnings of smoking cigarettes are widely publicized, and people know about the effects of second-hand smoke, yet most people are subject to far worse toxins on a daily basis, due to pollution of the environment.
You wouldn't disagree that living a healthy lifestyle increases one's lifespan, so why do you believe that there is ultimately still a limit on that? It only stands to reason that the more we learn about the effects of our environments on our bodies, and how to live more healthily, the longer we will live. The more we learn, the longer lifespans we could all ultimately live, and we can find ways to live forever if we choose to. I don't see anything wrong with that.
Animals, insects, bacterias that you mentioned have limited lifespans because they lack the intelligence to adapt and evolve. We as humans have evolved to a higher level of intelligence whereby we can learn and self-evolve much faster than any creature before us due to the intelligence we have. That's the difference there. Again, it's the same argument as with eating meat. The people who lack the ability to think with perspective (or simply just choose not to, perhaps due to lack of confidence in their own intelligence) argue that it's "natural" and that "animals eat meat so what's the difference".
The difference is that we have the higher state of intelligence to make a choice based upon our limitless capacity for knowledge.We make the choice, to kill (thereby not utilizing our intelligence, self-awareness and compassion and be just like less intelligent forms of life), or to find alternatives so that we don't have to kill.
And with this scenario, we as humans can make the choice to die, or to find alternatives so that we do not HAVE to die.
That's the ability that we (and only humans) have. If you choose not to utilize that capacity, well, in my opinion you are wasting your capacity as a human, but who am I to judge? You aren't going to stop my self-evolution, so you're only hurting yourself.
As Jokerman said earlier:
Listen. Those who want no part of this technology because they’re either ignorant or religious (as if that’s mutually exclusive) shouldn’t have any part of it. This world doesn’t need them living indefinitely. Natural Selection at work. See ya.
The people like you who stick to these limited, old school ways of thinking will die out. And those of us like Jokerman and I will continue to evolve, and continue to live, and the human race will become a more advanced species because of it.
