Human augmentation is a concept heavily represented in cyberpunk & science-fiction. What kind of cyber/ biohacking would you do to your body? Nanotech for enhanced healing & sight, to expand my color spectrum, something in the lines of Molly's clock in Neuromancer, yeah I would do that. Or headphones implanted in my auditory nerve. Sure cosmetic augmentations would also be pretty neat, like hydraulic limbs or or dermal armour.
