Illness for Vampires?

Vampires are undead and to me should be unique and not be plagued by the same type of things a so called living Sim would be plagued with. I am against undead sims or any other "creature" Sim being too much like the living, normal, sort of human sim. Injury and illness should be unique to the kind of sim one is playing - and different in my view.

I do like the fact creature sims can have babies (they are just to cute and precious not to have) but some where we need to draw the line from the Creature sims to the so called living, normal sims or at least options to not allow our creatures to be just like living sims. I enjoy the uniqueness and differences I feel between normal sims and all the rest and I would like the option to at least be there because I don't want my creatures just like my ordinary sims.
