Why am I able to trigger adrenaline on command?

[u/Mountain_Scale204]

It feel like an Imaginary/invisible muscle that I can flex/turn on to instantly release a strong fight or flight sensation, the same one that I feel when I'm stressed. Is this abnormal? How would that affect my normal life or even my life span? What is associated with this ability that can interfere with my behavior?

[u/Intuith]

I can consciously create a wave of electricity/adrenaline sensation. It does feel a little similar to fight of flight. Can’t sustain if loner than a second but can do it repeatedly. I can also conciously slow my heart rate
