Or how many people it could make not go to the ER, I went to the ER because I was having crazy heart palpitations I looked it up and started checking almost every symptom off the list of having a heart attack as it became more severe. I woke my wife up to drive me to the hospital, turned out I was fine, I was having a severe anxiety attack. Maybe something on my wrist that could help assure me that I’m okay might be a good thing, I think if I had one of these and saw that all was okay I wouldn’t have freaked out in the first place which mad me more and more panicked, mocking the symptoms more and more.
