Power Naps

I know I'm not the only one who has been in a meeting or class or just sitting and reading some document and found himself fighting back sleep. I'm sure others than myself have also noticed that if one succumbs to this urge, the actual rest time usually lasts only a few minutes and one then awakes refreshed and alert. Since we allow bathroom, coffee, and cigarette breaks, I propose that we allow nap breaks. Yes, naps can rage out of control. Yes, one should have tried to get a better night sleep or eaten a better breakfast (though sometimes this makes no difference). Yes, there are times, such as during one's presentations or while performing surgery, when a nap, however brief, cannot occur. Other than this, there is just the stigma and embarrassment of being found asleep and vulnerable (especially if one drools), but mandating such breaktimes at any location (or specifying special areas) would ease this problem and probably prevent numerous other problems (eg. math and writing errors) which we can attribute to lack of adequate rest.
