Yes, and I am seriously calling out everyone that voted "No, boredom," since that makes absolutely no sense.
The OP clearly states "Would you live as long as you could," which means that boredom is no longer a satisfactory explanation: As soon as it gets too boring, make yourself mortal again.
As for me, I'd go age-less in a heartbeat. I'll have all the time in the world to discover all of what we know about science and medicine. To be able to see evolution happening with my own eyes would be incredible.
