Is Indefinite Lifespan or Immortality possible?

'course you are. With stem cells especially. Right now, people get organ transplantation all the time. It doesn't change who they are as a person. Physiologically, they're attacking themselves from the inside out. But they're still themselves. no freaky "the eye" stuff going on there!

But with Stem Cells, especially YOUR OWN stem cells, you will essentially be REBUILDING your body. You think you've kept the same heart your entire life? Think again. Every cell in your body (except your brain, of course!) dies. That's what replication is for. Create a new cell before it dies. So the heart you have now is by no means the same heart as you had 2 years ago. It might not change overnight, but the cells do change. The question is, does it matter? The genetic material is 99.9% of the time exactly the same. So what's the difference?

 

i think a lifespan could be extended 10 fold if there was proper technology to replace our body. because after about 80 years our bodies start to break down, our cell division slows down and we get... OLD :nuts: which is fine by my, i dont want to live forever =] but if we were able to somehow reverse cell degeneration and prolong cell division who knows how long we could live.(unless a bus hits you, then your screwed.)

 

The span of time in which we humans live, as I think of it, is too short to comprehend our surroundings, to understand our purpose. Undoubtedly, there would be an unprecedented increase in science in technology. A scientist spends all of his life learning about a particular aspect and when he dies, all of that experience and knowledge passes away with him. Then, another scientist is born, it takes time for him to grow up and mature. Then, he might follow the path of the previous scientist. He would have spent so much time learning the same things which the other scientist had that indeed the time it would take forthis scientist to make innovations of his own would be limited. In the end, this scientist will also die, and thus, the cycle continues. The most important factor lost in this cycle is Time, the most precious and precarious thing there is. If only were we to overcome Time, then there would be little that would stand in the unparalleled development of Human civilization. The push for more living space for humans would force human expansion and colonization in all corners of the galaxy and the universe.

PS: If I could live forever, I would get a spaceship and explore the universe for aeons.

 

It'd be kind of lonely to live forever, surrounded by darkness...

 

I don't mind being lonely, The universe is so INFINITE!

 

Some scientists made a biomechanical heart, that replaces your old heart, so the people with them will not die of heart failures.I can't find the article though.

 

It might be possible to make your life longer with clones. For example, make a clone, when something fails on your body, you take the part from the clone. Very inhuman as you have to kill the clone and it will never happen, but well, it's possible.

 

Morals aside, if brain transplants were possible someone could live forever.

 

What about other organ failures?

 

No,

It's never gonna happen, especially when the world will end soon anyway -.-

 

To stop aging the cellular process would have to be stopped, therefore you would stop healing. Any injuries sustained during that time would last as long as your cells were in stasis. Therefore indefinite lifespan is possible but would have some disastrous after affects. If you were not fully grown you would stop growing but your brain would then age in relative experience and knowledge. Science now days cannot stop the cellular process, but it can slow it down to a point.

 

Stopping the process would kill you faster. Cells are constantly being replaced so if you stop them from producing them you would be dead in less then a month.

 

life is a constant cycle and death is part of that it needs to happen. plus at such an old age you're pretty much useless anyways i wouldn't want to be alive
