After day 600, the male mice just stopped defending their territory, listless mice congregated in the centres of the Universe. These gangs would burst into pointless and sporadic violence. Females stopped reproducing and even started attacking their own young. Mortality rose phenomenally. Roaming mice either attacked or attempted to mount others, irrespective of relation or gender, cannibalism and other acts of depravity consumed them. These were the feral ones. Then there were the ‘beautiful ones.’
The ‘beautiful ones’ withdrew themselves ever so quietly, removing themselves from the sick society. Solitary pursuits began to define them; eating, drinking and grooming among others. No scars on their back or hairs out-of-place, these mice behaved like a separate race. They saw the world through their narrow scopes, as they tossed, turned and tried to cope.
In the end the population sank, even when it was back down to a tolerable level none of the mice changed back. The change was irreversible, the mice were different now. The secluded females could still bear offspring and the beautiful ones had the capacity to help produce them yet it never came. This tipping over into irreversible societal collapse came to be known as ‘The Behavioral Sink.’ John Calhoun called it the first death. Death of the mind and soul, leading eventually to the second death, of the physical form. What he meant was that after the first death, the mice were no longer mice and could never be so again.
