No I'm not, in fact I wish I could live for as long as I want to. I'm into transhumanism and wish we could reach a point where our lifespans are very long to the point of being unlimited... That is unless there's an accident or the person chooses to end it.
I don't know if I'd ever want to die, I'd probably want to just sleep for a long time and then wake up hundreds of years later, or if possible, upload my mind and live a thousand of different lives in many different worlds, be it realistic or fantasy based. I want to see the future, I want to experience space travel and maybe living on other planets. There's so many possibilities!
However I do not believe in an afterlife or a creator god that made heaven. If this sort of technology never happens in my lifetime, then I'm just going to pass away. I accept that. I'm not scared of death, in fact I'd say I'm more scared of pain. I just want to experience many things and one short life isn't enough.
