adrenaline

Psychology tells us that anger makes us feel more powerful because of the adrenaline that courses through our bodies prior to acting out.

"The rugby gives you the most contact, the most adrenaline. Table tennis is great but there is no real adrenaline rush off it!"

Willis says that spending time outdoors lowers levels of cortisol and adrenaline - the hormones that surge when you're stressed or anxious.

The movie ultimately treats us like adrenaline junkies, assuming we lack curiosity.

"An adrenaline rush, an ego boost, a full sense of worth, a selfish gratification with no rewards, at cost to others. What I lost, what we have lost, cannot be found nor replaced."
