On ‘Amok Time’ I don’t remember if it was Gene Roddenberry, Gene Coon or [writer] Ted Sturgeon who came up with the idea of the Vulcan seven-year mating cycle, but the way we established it, Vulcans mate normally anytime they want to. However, every seven years you do the ritual, the ceremony, the whole thing. It’s a biological urge. This every seven-years business was taken literally by too many people who aren’t stopping and understanding. I mean, every seven years would be a little bad, and it would not explain the Vulcans of many different ages, which are not seven years apart.
