Knot, I think you read my mind. I also thought that this bracelet would be great for the trucking industry. Actually, I think any company, such as WALMART, may want to invest in these bracelets and provide them for all their drivers and make it mandatory to wear them. If you recall, it was a Walmart truck that collided with the limo Tracy Morgan was in. They said that driver had been awake for 24 hours and that he fell asleep, causing that accident.
