I have never seen a medic using an AED in real life. I see this machine in action only in movies and TV shows. Deep inside, I would really not like to see one being used in real life because that would mean a person is down and is being zapped to life. That is quite a traumatic sight to see. I think it will leave a stigma to me for the rest of my life.
That must be one of the reasons I did not pursue medicine. I don't think I can see life and death in a more scientific way. These two will always have a spiritual meaning to me.
