Unlike the average person, Graham has a ribcage full of airbags to absorb force and safeguard his organs. Cradling these sacks is a big chest with strong ribs. Graham's skull is meant to absorb force too, and is built thick like a helmet. It's got built-in crumple zones too, to slow his head as it lurches forward in a crash. Extra cerebrospinal fluid cushions his brain, while facial fat offers padding around his ears and nose (which is flat, to keep from breaking).
