“Someone sneaks up behind you and shouts, “Boo!” For a few seconds your heart beats faster. You did not run or do any physical activity that would increase your heart rate. What caused your heart to beat so fast?”

Your heart beats vigorously as you calm down from the sudden scare. What you just felt was adrenaline pumping through your veins. It is activated when you feel danger. Because of adrenaline, in a life or death situation, you can run faster or fight stronger. Those stories of people lifting heavy objects to save their families or friends aren’t made up. Because of the sudden adrenaline rush, you are able to do things you normally wouldn’t. I have experienced this first hand. Once, my grandmother fell off of her motorized scooter and I had to lift it up, so she could stand. Normally, I wouldn’t be able to lift something as heavy as it was, but the adrenaline rush pushed me further than my usual limits. So next time you’re in a life or death situation, thank the adrenaline running through your veins for helping you survive.
