B O D Y
This aspect involves action, novelty, entertainment, and experiencing life. Temperament theory describes this aspect as the SP "Artisan" temperament.
For this aspect, thinking and feeling and belonging are all very nice, but sometimes it's necessary to do something. Even the results don't matter so much as long as something is happening.
As this is the least-developed of the four aspects of my personality, there's not a lot of impressive experience to relate. Although I've been hang-gliding and whitewater rafting, and have a perverse desire to own and fly ultralight aircaft, most of my "action" consists of relatively solitary activities.
My Feeling action is expressed in Writing; my occasional taste for novelty is satisfied by Travel; my need for action that fulfills socially useful duties is met through Work; and I exercise my mind with Games--call it calisthenics for the brain.
