Endorphins.

All subjects are releasing Endorphins , that bind onto neurone receptors . Which reduces the perception of pain and also triggers a positive feeling in the body. Overall it is accompanied by an energising outlook on life. The word is an abbreviation of " endogenous morphine", which means a morphine like substance naturally produced in the body. Focus is locked onto a range of activities that influence or inevitably produce endorphins . Capturing these through their expression and body language was my aim.
