Therapeutic Beauty.

I keep reminding myself to listen to the music more often, just as I should always carry around a water bottle.

It actually has a very practical, tangible value. It affects the mood, the psyche and, hence, productivity. Better arts does mean better services and consumer goods.

I've read somewhere that your average westerner is badly dehydrated most of the day, which makes a water bottle a living necessity. The same goes for an i-pod.
