Are You Sleep Deprived?

Sleep deprivation is a really serious issue for society. It's estimated that about 20 % of car accidents and near crashes are related to driver fatigue. But consider that we don't have any laws against driving when you're tired. There are many professions where sleep deprivation can lead to disasters. And i think what we'd like to do with time is to develop measures of when these local sleep waves are rising and have hit a certain threshold, so we can alarm people before they fall asleep"
