Simple question. If given the choice, would you want to live forever, or maybe only for the next 500 years. I'm not talking about being 100 years old with a 100 year old body, frail, but with a mind and body and the ability to do anything you want. It's often said that "youth is wasted on the young". Sometimes one might think that by the time a person get's life somewhat figured out you're too old to do anything about it. What if you could continue to apply everything you know to your life?  
 
The scenario is that only YOU are living a long, long time, not everybody. Would you still choose to move along?  
 
I think four thousand years ago when many things did not change too much for hundreds of years I might not choose to live a very long life but now, with the continual leaps and bounds of knowledge and technology it would be interesting to see how the next 500 years would play out for humanity. Would we at some point put aside our differences, would we get to explore more of the universe? With what we know now, all of our collective knowledge, what will we know in the next 100, 400 or even 1,000 years?

yes.  
No question.  
I have way too much curiosity to ever want to die before i know what's going to happen next.  
 
No problem with it being just me, you'd quickly get used to other people only being around for a short while.  
But the idea of dying really really annoys me.

No way (kind of). Sure there's things like all of your friends dying and stuff like that, but this isn't my home.
 
 I'm a Christain, when my time comes to die I won't be screaming for a few more years, days, or seconds, I'll just accept it. Act of Valor really hit me about being ready to die too.
 
Also I will live forever, just not here (which is the question). And I'd rather spend my time in Heaven than here.
 
I'm sure when I get older I'll see a lot of amazing places and things and there will always be more to see and to do, however, that's not why I'm here.  
 
So, a simple No for me, others will probably choose differently but those are just my reasons.

Absolutely.  If there is one thing the tragic death of family members has taught me, it's that the only person I can't live without is myself.  I'm actually really hoping science cures senescence (aging) so that we can all live forever if we so choose.  I think that should be medicine's number one priority, as aging kills more people than anything else.  It's a plague we shouldn't have to put up with any longer.

It might be interesting to see the End when the Sun exhausts it's nuclear fuel and expands to encompass the orbit of Mars, effectively rendering all the inner planets to cinders...  
 
But that's some billions of years in the future so it'd be a long wait.
 
By "live forever" most mean "in a good state of physical vigor and mental acuity".   At 65, mortality seems rather too short at present...  
I wouldnt' mind hanging in there in a healthy state for another 100 years or so.....  
 
There are those who study aging that think this may be acheivable at some point.  We know that cell division is limited by certain aspects of the structure of DNA.  It's thought that if the self-limiting genes could be altered or removed, there would not be any impediment to a constantly self-repairing body.
 
Then there's the idea that we could upload our consciousness into a computer and live "virtually" for as long as we liked... Or until the system crashed.   This has been kicked around for years; would require several quantum increases in computing power and interface technology, but most acknowledge the possibility.

And if I imagine myself sanding boats or adjusting engines at the age of 140 - after about 120 years of this simple and not fatiguing job, I'm prone to commit suicide.  
Please, leave Methuselah to the Bible.
Greetings,
Mauro.

I disagree.  I think generational turnover, and the aging process both represent tremendous losses.  I think it would be really cool if I could go talk to somebody in good health with a sound mind who remembered the American Civil War or the Revolution, or the Crusades, or the conquest of Gaul.  Those things would be staggeringly cool.  These days, you're lucky if you can still talk to someone of sound mind who remembers World War II.
