I chose option two which is a reflection on Kelly McGonigal. McGonigal started off with a study on 30,000 Americans asking how much stress they experienced? They were also asked if they believed stress was harmful. Then the researcher checked the death rates. People who believed stress is harmful for their health had a 43% higher chance of dying. People who did not believe stress was harmful were least likely to die. 20,000 people died from stress according to McGonigal. That would mean that changing what you think about stress would make you healthier. Then McGonigal explains the research that if you rethink your biological reaction to stress as this is my body preparing me for a situation. The heart pumping fast is to get more oxygen to your brain. Then she moves on to Oxycontin explaining it is just as a stress response as your heart pumping. Oxycontin makes sure you tell people you and get that support in stressful situations. Oxycontin helps repair your heart in social situations. A person then releases more Oxycontin when people interact with people. Caring for others can counteract the stress.
I think the speaker is credible because scientifically that is sound. She is a Professor at Stanford so that also heightens her credibility. I agree with her also because physiologically there are a lot of examples where a persons mindset changes the outcome of an event. For example if you believe you cannot do something you automatically shut down or or subconsciously do not try as hard. In my life I feel this way about Chemistry I must change my mindset about it. I do not hate chemistry it is not too hard and then i can focus. I could implement this into my life by simply believing that the Adrenalin response at exam time is to help me preform at my prime. I can also manipulate Oxycontin to repair my heart as Mcgonigal suggested.
