A body is a biological machine. Once we have mastered learning about how it works on every level we can (will) redesign it into perfection. Sooner or later immortality will be achieved. Not by magic, but by slow progression. We will make a list of all the potential causes of death and start crossing them off. First will be aging, then at some point we will master the complexities of the immune system to be able to handle any sort of threatening bacteria, etc... Of course there will always be death from non natural causes like getting hit by a bus or getting shot. But stem cell regeneration will make all but the most fatal (like getting shot in the face 6 times) injuries treatable as well.
