Polygamy is illegal in the United States, Canada, Australia, and Europe but is allowed in some African, Middle Eastern, and Asian countries.

If you have more than one life, you are Reincarnated. This is a belief of Hindus and it means when you die, you are reborn. There is no term for having more than one life, but the act of having multiple lives is Reincarnation. Hope this helps.
