Welcome to the forum DistantLaughter !
Just a note for something to look out for here on the forum regarding "katastematic pleasure" that there is some variance in how members here on the forum define and apply that.
I myself have ideas about it that I have yet to fully develop. Also, it is based on the larger context of "choice and avoidance" and it is going to be understood and applied differently depending on variations of extroversion/introversion (and also differences in physiological stress tolerance).
