I certainly can imagine life that is worth living forever and ever. But whether that's possible or not is another story.
No food dependence, the ability to trek endless distances, nothing but virtues to live, perfect superintelligence, throw in the u.s.s. Enterprise, portality, artificial life, endless dignified life forms, federation and Jedi cultures and civilizations, and alien world's and civilizations, music, fine art, and a one true wife, disciplines and challenges in everything, and time for perfect peaceful rest, love beyond ever measuring, and creation science for the ability to create anything. Create knowledge, and an infinity of things, and I sign up for eternal life.
Lol. Perhaps some noble adversaries too. None evil though.
Give me all that and I will
