Living forever would be depressing, everyone around you would always die. You could literally never get close to people anymore because you eventually have to detach yourself from them emotionally. I would probably want to die eventually if aging still exists but I definitely want to live a long time though, maybe a million years or something crazy so I could learn as much as I can and have as many awesome experiences as I can.
If the hypothetical idea of an afterlife means more to you than the objectively true reality we all share, then you deserve no respect.
