Glad you asked.
Once upon a time in a book store long ago ( do you remember them or are you too young) I thumbed through a book of symptoms of disease possibilities. I was considering buying it but then common sense prevailed and I didn't. Why?
Because I'd be dying of this or that or the other thing. I saw no point in that. I know me too well. So I passed.
Can you be trusted to own a book like that and not go to your special crazy place and worry unnecessarily?
I know I can't.
