Well longing for an infinite lifespan / immortality is a rather silly attitude if you look closer. Denying death means denying life itself as both are connected. You mustn't focus on death because it's inevidable in our current world and you totally miss life with that attitude...

Immortal things of any kind are impossible in this world of ours. As all we know exists under the "bondage" of time everything has a start and this way an end too. Only what isn't influenced by time can be truly immortal and is beyond our current imagination...
