Thank you for the unhelpful answer, I'm just curious how much time did it take you to copy/paste such an answer?

And the content was not copy-pasted: it was edited into lay terms from a medical source so it becomes clear and understandable to you.
In any case, if you find my response unhelpful, I'm sure my colleagues can add their opinions which you will hopefully find more helpful.
