What do you mean, you meant to say no?

It has long been known that Grocery Shopping While Hungry is the Number 1 economic driver of the cupboard and steel industries, as homeowners and supermarket chains struggle to have enough carts and storage space for everything that "looks good" to a ravenous person.

Despite volumes of empirical data supporting that conclusion, most people ignore it. So it's unknown whether the public will give more, or any, weight to a recent unrelated -- but equally interesting -- discovery:

Human interaction under the influence of caffeine is what propels those who want more hours in a day. Try 32, perhaps.

This new research shows that coffee drinkers  volunteer for (or consent to) six times the number of tasks and four times the number of board appointments as a sane person would.

The phenomenon is marked by several distinctive phases: 

1) The initial acknowledgment that someone had a good idea. 
2) A regrettable reluctance to respond to it with a firm: "Why don't you do it yourself?"
3) The caffeinated brain's pivotal "I can take care of THAT." 
4) The unexplained failure of those listening to hear the limitations of THAT (as in: only THAT), resulting in an unintended commitment to THAT and anything connected to THAT into perpetuity.
5) The conviction that saying "yes" is reasonable, will ultimately save time, and may even be enjoyable.

Despite the length to which researchers have studied this, there is still one facet of the discovery they can't explain:  Why is the effect of caffeine limited to "The same people who always do everything." Why are those who have no problem saying "no" unscathed?
Stay tuned for developments.
