[@Mistiel] But would they not still engage in sex as a primary means of bonding? Without verbal intimacy, phsyical intimacy is really all you have left, and if there was no more sex, due to test tube babies, and such, I feel like the suicide rates would skyrocket due to neurotransmitter imbalances causing severe depression and anxiety without a cure, and due to the isolation, Seattle would be hard pressed to aquire a number of pharmaceutical ingredients.

EDIT: Unless you continued Seattle's trend of marijuana usage.
