You can look around while hacking, it's just akward.
Jensen being the only augment who doesn't need Neuroprozyne to prevent rejection is actually an important point of the story, it all gets explained in the end.
It's important to remember that Jensen didn't WANT to be augmented and he was the voice of doubt at the beginning, after his 'accident' he was basically butchered- his arms and legs were all cut off, his heart robotically enhanced/replaced, several of his organs replaced, his brain and eyes heavily augmented though not outright replaced. He's more machine than man now.

If you dig around, Megan's groundbreaking research involves genetic material from a human subject called "Patient X" with the completly unique physiology that readily accepts augmentation and doesn't require Neuroprozyne injections. Using gene therapy and tweaked tech based on Patient X's nervous system, she can make augments ANYONE can use without ANY rejection.
Jensen is Patient X. It is revealed he was adopted by the Jensens, being the product of an illuminati test lab that was trying to produced an evolved human baby by systematically exposing dozens of children to fatal illnesses to produce a more evolved human being. Essentially, they were murdering babies to speed up evolution and produce an ubermensch. Adam was the product of those experiments. When his biological parents realized that the experiments were going to countinue even after adam was produced and more children would die, they burned the facility to the ground to stop it from happening, and Adam was whisked away to be given up to a family that wanted a child - the Jensens.
After Jensen's injuries, Sarif replaces at least 70% of Adam's body with augments, far and above what he actually NEEDED (he just needed an arm replaced and some chest reconstruction) simply to see how far he could possibly push Jensens evolved body. All the augments you 'purchase' in the game are already installed in his body, but his brain and nervous system simply couldn't handle them all being turned on at once before he finished convalescence, so they automatically switch on over time - the EXP system, and why you get a praxis point every so often for gaining exp and 'leveling up'. Alternativly you can simply find or purchase praxis software to force the switch to on, since there's no time to go under the knife and have it all done manually. He's not 'willingly' getting new augments, they were all already forced on him - and they're going to turn on on their own eventually. He can only accellerate the process.
