Anti-sleep alarm

As satisfying as napping may be, the nodding off head-bob looks good on no one. Spare yourself the embarrassment with an Anti-Sleep Driving Alarm. Designed to prevent people from falling asleep at the wheel, the little ear buds issue a high-pitched alarm if your held tilts forward more than 30 degrees. Just remember to take them out in the unlikely event that you ever choose to take notes.
