I found this sentence in a book about anxiety and how to treat it. The author here is speaking about the fight-or-flight response of human body (see here: https://en.wikipedia.org/wiki/Fight-or-flight_response ). I don’t understand the meaning of the first sentence. What does it mean «thrive on adrenaline» here?
Many of us thrive on adrenaline in fight-or-flight mode based on life-style, external demands, or the way we react to stressors. Although welcomed at moments of need, unmanaged excessive demand of adrenaline can drive imbalanced expression, which results in anxiety, panic attack, worry etc.
