“No guilt is forgotten so long as the conscience still knows of it.”

This year’s drought has motivated California to invest $1 billion in new money on water recycling efforts statewide, a much more cost-efficient way of increasing potable water supplies.

In one often-cited experiment, researchers poured clean apple juice into a clean bedpan, and asked participants if they’d be comfortable drinking the apple juice afterwards.
