Star Trek: Every seven years or so, Vulcan males and females become aroused.
They undergo a blood fever, become violent, and finally die unless they
mate with someone with whom they are emphatically bonded or engage in
the ritual battle known as kal-if-fee. This was known, in the series, as pon farr - In my world, this was also known as a 'coming of manhood or age'! A time when hormonal secretions, acting in a young male body, were at their height! (A good time, I think most of us men would agree)!
