No matter how many times she encountered the Eagle, her adrenaline level always increased in his presence.

My own adrenaline level was so high, I could easily have carried her all the way myself.

Then he could study the effect of stress on her adrenaline levels.

Often a decrease in activity level is noted as adrenaline levels fall.

Those experiencing rage usually feel the effects of high adrenaline levels in the body.

But he is at his best when he changes the adrenaline level.

As my adrenaline level began its descent to normal, I looked back at her.

If he stops or pauses, the adrenaline levels of his body return to normal.

Even though the adrenaline level was up, her nerves were steady.

You can startle her, but there's no increase in adrenaline levels.
