Yes very interesting @suesa
I understand from your picture, and I have read your story.
I can say the key to the problem is because of a sudden high heart rate. A person's heartbeat can occur suddenly because there are several factors, such as shock, and can also because of seeing something that has never been seen.
That is why, a person can cause a stroke. If that had happened, then the disaster for that person, because the stroke is a dangerous and deadly disease.
Thank you @suesa: good post.
