General Anesthesia

One of my friends told me that she took a day off yesterday, and went to a hospital to have a medical test. The test performed under general anesthesia which was given through a mask. She remembered to take a few breaths and felt a nurse tapping her arm. She thought nothing hadn’t started, but the test was already over. We were talking about some drama scenes where someone was made to sleep with a cloth over their faces. We thought that those scenes were exaggerated, but her experience at the hospital showed how fast unconsciousness can happen.
