I'd be really interested in how religion would develop in an immortal society. The removal of guaranteed death, and the diminished precedence of the afterlife, would have a large effect on how religion developed.
Disease will sooner or later be conquered as well. Just need to fine tune the human immune system and bolster it to be able to fend off the most deadly diseases.

There is a clear way on maintaining the current lifestyle but it would take massive social upheavals to undertake them. However, given the opportunity of either a lower standard of living or switching the structure of their respective countries to the alternative plan, many countries and societies will choose the alternative path.
