Living forever would be cool as long as our technology could make sure we're off this planet and somewhere comfortable by the time our sun goes red giant (also: forever as a relatively healthy, ageless 30 something).
I'm in no way looking forward my eventual death... I really like living, and the odds are that death is going to be pretty anticlimactic... I mean, you just stop being. You don't know you're dead, you're just compost. I'm too stoked on existing and being self-aware to want to experience an end to it all. I seriously doubt there's any afterlife, so death really doesn't offer an incentive.
