If immortality does not preclude the option of suicide, I'd like it. But there are problems even then. If we all get immortality, it's going to get crowded and our children will lose some basic things we have. If you are contemplating immortality in heaven, then I have a hard time imagining it as anything other than infinite boredom or infinite know towing and infinite boredom. Reincarnation sounds better provided one could choose real permanent death if endless death and rebirth became too repetitive.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
