Yes, I would want to live forever, IF...
I could always learn new things, make new friends, do good for others, and make the world an ever better place, then yes, the answer is yes.
That is a damn big IF.....
I don't think I would want to, even if all those things would occur. Because there will always be sadness, too. Even though you could make new friends, old ones will die, and family will be gone, too. Plus with all the craziness going on, who would want to live through another 9/11? You are talking about Utopia, which doesn't exist now. Who says it will exist later????
And what about money and sustaining your lifestyle? I am assuming that you would want that, too???
