you really mean how long till we cure ageing, imortality would require a way to combat all diseases and accidents...
it would be a disater if it happened before we have the ability to travel between stars or at least build massive habitable space structures (like ring world)
it would also probably cause ww3.... since faced with imortality you would ahve to plan 100's or 1000's (if not more) years in advance and secure resources
