What caused me to write this

It is that I thought that I would write about brain death by the death of my grandmother.
My grandmother passed away on December 26 last year. It was the first death of any of my relatives . I was crying every day.I could not accept the reality of death easily .Then on a certain day,I watched the news which was about brain death . I was very interested in the topic because thought about the means of Life and Death I want to write my opinion about brain death through thinking about Life and Death.
