Actually, even with the consequences you people are proclaiming I still would really be willing to trade most things to become immortal. Eventually If I would not be able to control my emotions I would edit my genetic code and delete the very information that allows me too feel such a thing.
After that I would wait trillions of years until the last stars of the universe are extinguished; afterwards I'll construct my own galaxy and life on it. I would create a galactic mausoleum in the center of the galaxy.
When a sentient dies it is brought there to the illustrious object which is pulling with immense gravitational forces that bond the very chains of the galaxy together, and buried there within the catacombs upon catacombs like a labyrinth of tombs. I would sit in the very center of it, surrounded with my own creations.
There would be pipes stretching from the surface of the object, detecting EM patterns and amplifying them through out the chambers of the cemetery world like the pipes of an organ transporting ancient sounds that are perhaps thousands of years old by the time I'll hear them.
