I would augment my body with the only chance of survival a life made of squishy organs has.
Mechanical.
No matter what you do or how careful you are, eventually, an organism will die. Machines, on the other hand, can technically live forever with part replacements and upgrades. I agree with Bender on one matter; life is pointless short of immortality. The only true hurdle for that is just brain-to-[storage device here], and from there, it's nothing more than making a computer with robotic arms and wheels.
Oh wait. I got a bit too into it, didn't I? No matter. My points still stands. Besides, at that point I'm able to both overcome the inevitable crippling of carpal tunnel syndrome and also enjoy video games on a level far beyond that which we can comprehend now.
