Human

Human is the life state a sim is born or created with. It can also be considered "normal" i.e. lacking a life state. Unlike the other life states, being human does not offer any pros or cons, although, that in itself, can be seen as a pro or con.

Compatibility
Unlike the other life states, if a human turns to another life state, he/she will cease to be human. i.e. If a Vampire is attacked by a werewolf, the vampire will remain a vampire, and also become a werewolf. However, if a Human is attacked by a vampire the human will cease to be a human, and become a full vampire. Thus it is impossible to make human-Hybrids, except in the case of Aliens, but this is caused by genetics, rather than a life state being transferred as in the case of a werewolf's savage or a vampire's bite neck.
