[Metal Gear Rising: Revengeance] How do cyborgs like Raiden and Sam... live outside of missions? Like, can they relax and enjoy entertainment? Don't all the modifications on their body make it impossible to live a full life outside fighting?

Settings with millitary-focused body modification (Camille from LoL, cyborgs in Metal Gear, things like that) always confused me... as those mods seem to make living a normal life impossible.

Sam isn't a cyborg, the only cybernetics he has is his arm. He can just take his strength suit off and be a normal dude. He'll still have his cyborg arm but it's not a huge inconvenience. 

Raiden' situation is a bit different, he's fully cybernetic except for like...an eye. He does have a wife and child however, so when he's off a mission he just spends time with them. Also Raiden after MGR gets a much more human looking body than the custom cyborg body he had during his fight against world marshal. He can blend in just fine.

But you have to keep in mind. Fighting is their life, they love doing that shit.
