Why do humans procrastinate?
There was a recent highly cited paper describing the concept of willpower as a measurable, physiological, depletable quantity, strongly affected by glucose levels:<p><a href="http://www.fed.cuhk.edu.hk/~lchang/material/Evolutionary/Brain/Self-control%20relies%20on%20glucose%20as%20a%20limited%20energy%20source%20willpower%20Is%20more%20than%20a%20metaphor.pdf" rel="nofollow">http://www.fed.cuhk.edu.hk/~lchang/material/Evolutionary/Bra...</a><p>And there was a very interesting Metafilter thread from a few years ago that found that a small amount of alcohol overcame procrastination:<p><a href="http://ask.metafilter.com/22924/Why-does-alcohol-overcome-my-procrastination" rel="nofollow">http://ask.metafilter.com/22924/Why-does-alcohol-overcome-my...</a><p>It's probably time to start studying these kinds of things as genuinely biological phenomena.
