Johnsonverse World History/Cosmetic

==Human biology==
There is one minute difference with human biology in the Johnsonverse, in that the refractory period does not exist. There is evidence that it did in the past, but in direct response to the Toba Catastrophe reducing the human population to roughly 1,000 to 10,000, humans evolved to lose this to enable rapid repopulation. Consequently, amateur pornography in the Johnsonverse tend to be much longer in runtime.
