Will you get visible scars? 'cause that'd be awesome.
You could use it as a way to pick up chicks. Tell them that you're an evil crazy doctor, and that the scars are where you opened yourself up to make yourself a human-robot hybrid. You opened up your chest to replace your heart with a fusion-driven heart like in Ironman, and then you replaced your ribcage and bone structure with titanium dioboride fullerene-reinforced steel. Make sure to stress the point that this means you can go on like a Duracell rabbit - if you get my point.
If she asks you what that is, tell her the truth that your skeleton is now made up of titanium dioboride layered with a mix of fullerene and iron, thus making an extremely durable steel isotope that can not be destroyed - except for your spine, which is only reinforced in order to allow the continued production of blood, as you are yet to discover a way to continue the production of white blood cells without your spinal fluid. Everyone has to have an Achiles Heel, no?
