Procrastination: a skill we've mastered

I consider myself pretty organized. I keep appointments on a calendar and carry my PDA with me at all times, but I also tend to procrastinate, putting off things I don't want to do -- usually unpleasant, confrontational stuff. I'm not alone. Researchers say we're doing more procrastinating, and we're getting fatter and unhappier because of it.
Sometimes I think we all need a Mommy to nag us into good behavior. Or at least an embedded chip that shocks us into taking the bull by the horn. After all, there's a real pleasure in scratching something off the To-Do List.
