I've been asked, and thought about it, for some time. I have decided that my answer is NO, I do not what to live forever, on this plain of existence.
As I progress though this earthly existence, from the day I was born 'till today (well over 7 decades) ... I am sure I do not want to stay forever.
As it is, I am still here, yet so many of my family, friends, comrades-in-arms, are gone.
So why would I want to stay? I don't. I'll take no action to hasten my departure... but when it comes, I'll be OK with it.
