Oh dear.
My twisted mind just came up with a horrific short story for this theme.
An idea that only a sick psychopathic serial killer would probably conceive of...

Should I start worrying about my mental health?
Or should you all start worrying about your physical health when I'm around?
Dun dun duuun!

But no really it's a clever idea and possibly good story telling but the end result is just...
Morbid.
