It's not quite what I'd call immortality, and it sounds like you mean on a population wide scale of availability (not just me personally). So I would have to answer: no. It's part of a species' strength to be able to adapt and change. The old teach the new how to avoid their mistakes. I don't know that we can account for all the ramifications for completely scratching the tried and true birth & death population mechanics. Are we mentally prepared to live forever, barring any death or injury from something outside our own body? I think that the overturning of our generations grants some advantages that we take for granted such as the influx of fresh, new ideas.
However, were this a "genie in a bottle wish," I think that I would take it. I'm curious to see what happens after my time to humanity. It's a double standard, which makes me uncomfortable, but given the circumstances of each, I think my answers are understandable.
