There may be 3 billion women maybe on this "plant", but that takes into account the old and young, therefore the possibilities are less than three billion. Then we must also take into account how much this person gets around, which judging by his thread, is little to none, so the possibilities are diminished yet again. Then we have to also account for compatibility, which takes another toll on the amount of possibilities. So in other words there may be 3 billion women, but there is not a chance of having 3 billion possibilities.
