So today I was listening to the classic news station and they had a bit about a pro-life bill being passed in Mississippi where life is being defined as starting at conception. [This contrasts quite sharply with Dave Barry's notion that abortions are legal until age 21.] Also mulling about in my thoughts were the implications of the semminal court case on the matter Roe v. Wade. But I think the best answer to when does life begin is offered by the Mormons. Given a pre-mortal existence, life actually begins BEFORE conception! Which of course means that, it is a sin and you are a murderer if you even THINK about not having kids.
