Big X2!
As for the immortality bit, well there is a lot being done in an attempt to make humans biologically immortal. I actually didn't know this before, but there are some species of jellyfish that are biologically immortal, and actually can make themselves younger! Brilliant minds are at work trying to replicate those processes, but that breakthrough is probably several centuries away from being truly realized.
In the near future, there will be advances that will add years, maybe even decades to the average lifespan, however.
