    Nani, just because you have a nervous system doesn't mean you feel pain. There is virtually nothing besides the most primitive centralized NVS in the animal kingdom. The body cavity is little to none, and there is no pain, not even physical pain let alone "realization" of pain like Humans, and only humans, can realize.

  • They can feel pain, what are you talking about? Their little earlobes are sensitive to touch, and they're among the simplest life forms to have a central nervous system.

  • Singular-Planarian, Plural-Planaria i guess...

  • crip

  • The awesome power of regenerating heads...
