Answer 1

Opioids like heroin are sedatives. They affect the brain with a euphoric feelings then extreme lethargy. So imagine yourself having stayed awake all night then run 1 mile in the snow at a good pace. Now go to a simple room that has the heater racked to about 78 F and listen to a 1950’s radio program detailing Keynesian economic theory and try to take notes. That situational effort of you trying to stay awake is what your asking.
