I’d take immortality—you can always “give back the gift” (to quote Aragorn in Lord of the Rings).
That said, how long would you like to live? 500 years? 1,000 years? Would you get the urge to make a new family every 30 years or so? Would your kids live 500 years or 1,000 years? With everyone doing that, how quickly would we exceed the earth's carrying capacity? Keeping life interesting would be a challenge. There are so many things that are best enjoyed the first time, that get stale when repeated: loves, careers, so forth. Schopenhauer said something quite profound: "Living a long time is like staying too long at the conjurer's booth at the fair; the tricks are meant to be seen only once."
No thanks. As much as I try to live a Godly life, I fail all day long and sometimes I despair of ever being a decent person. I could not stomach living forever in my present state. Likely things would get worse not better and I would never have the hope that one day in the not-too-distant future I can be in the presence of my Lord and Savior and will become incorruptible.
Why would want to hang on to this old body when I have a much better one coming soon enough?
