In order to broaden the function of toilet paper, I think it would be a good thing to build in indicator-paper, and be able to check the pH-factor (of course first we should know the normal pH-factor).

So after using the toiletpaper, check the color (of the paper!) and see if you need to eat more vitamins, or, in the worst case, need to go to the doc.

Why not the toilet water instead ? Just in case you don't want pH detector chemicals in your arse. I'm imagining traces of healthy bright-red (or whatever) pH dye leaching onto one's underwear. Mmm, nice colourful patch wherever you sit.

Oh yeh, angel's link.
