A View of DeathDo people really think about death?
I'm quite OCD when it comes to grammar and punctuation, etc. So, I was stumbling through your prose. However, there is a silver lining...
Your prose follows your thought process which makes this piece a bit more personal to the reader. And, you ask a lot of questions many of us have, so you ideas are relevant.
Try honing your literary tools to express your thoughts more clearly.
"Brian function is biologically dictated..." (misspelling).
"How much Catholics and Christians in the world?" (grammar).
Take your time and review your writing. I know that many writers write from the fountain of insight that seems to grace us all at a moments' notice. Still, we must remember to sit back and review what we have written, to preserve clarity and creativity.
