Stuff we should do and don't

A study in Germany (from the University of Leubeck, wherever that is) shows that creativity and problem-solving appear to be directly linked to adequate sleep...and defined as adequate "eight hours of rest." Words like "huge difference in mental performance" and "good reason to respect our periods of sleep" showed up.

I started to write about studies that spend their grant money to determine what is pretty much common sense...but then I got to thinking about why we don't apply these areas of common sense.

You know, over the last year or so I've seen studies on things like...

*eating healthy with the occasional splurge instead of the other way around.
*excercising regularly.
*reading more.
*watching less television.
*have sit-down meals instead of wolfing it down in the van on the way to somewhere.
*cutting out or back on soft drinks/coffee.
*avoiding anger.

Things like that. Sure, we can giggle at the fact that some doctor at some university put a bunch of people in a study and then "proved" to us that "weight loss can be attributed to more excercise and strict diet" but why don't we generally apply these common sense things?
