Adrenaline!!!

What is it?
Epinephrine also known as adrenaline is a hormone and a neurotransmitter. It increases heart rate, constricts blood vessels, dilates air passages and participates in the fight-or-flight response of the sympathetic nervous system. Chemically, epinephrine is a catecholamine, a monoamine produced only by the adrenal glands from the amino acids phenylalanine and tyrosine.


How does adrenaline work in the human body?
The adrenal glands may be found directly above the kidneys in the human body, and are roughly 3 inches (7.62 cm) in length. Norepinephrine  is also released from the adrenal glands when they are active.


People's experiences:


Here's a opinion of someone who loves the adrenaline:  " I am addicted to falling through the air, whether it be skydiving, bungee jumping or my new personal favorite, human slingshotting!
That rush of fear makes me feel so alive and reminds me how limited our time in this life is and renews my determination to experience as much as I possibly can"
My own experiences:
I use the adrenaline when doing sports or fighting. It feels that you are flying, that nothing can stop you. You can feel the anger and the focus of your mind and your body . And then you stop, everything turns quiet and slow, you see everyone and everything..... the time stops.
