I think science is going too far. It's unnatural in my opinion. We are supposed to die.

Death is as an important part of our existence as life itself. As we age our maturity and roles in life change again and again. We are reborn many times in a healthy life and roles like being a teacher, mentor and a protector are just as important when we are older, for ourselves, as the they are for the young people we are teaching and protecting. It's this psychological and physiological evolution that transcends us, gives us reflection, puts context to life and brings us closer to "understanding".

Without this process, given infinite time, life would become meaningless. Sitting around watching television would have just as much value as building bridges, growing trees or taking drugs. The majority of the human race would descend into complete hedonism. There would be no "meaning" to life other than experience. There would be no chapters, there would be no context, no celebration of new life, no reverence for the passed. Just an endless passage of time.

Some would become involved with the pursuits of deeper learning. The vast majority would continue blindly though as they do today. That would sooner or later lead to suicide. Our race of immortals would start to knock themselves off at astounding rates once the pointlessness sets in and fatalistic psychology caught hold. It's happened before in small isolated towns. That's rather ironic really.

So no... we're not jellyfish. I vote nay.
