You know, now my idea doesn't sound so crazy.
I was changing my 2nd cousin a few weeks ago, and I thought "Gee it sure would be nice if someone would wipe MY ass." Then I thought, well hell, would there be a market to have personal asswipers at spas and such? You'd go in, do your business, then prop up on a table. Person would come along, use some baby wipes to make sure it's nice and clean. Maybe put some ointment on if there was anything funky going on. Top it all off with some baby powder.
Yea, I really don't know wtf I was thinking.
However, I'd definitely pay for an adjustable toilet. I go into bathrooms and friends house and the damn things too damn low. My knees are almost hitting my chin. Then I go home and I have the Mt. Everest of toilets that I'd be more comfortable with a step stool under my feet.
