     In the morning, blue light helps, and during the day, bright day-   
     light helps set your internal clock. Older guys have yellowed   
     eyes and fewer receptors, which is why they see less blue.   
     This can mess with their internal clock and, by extension,   
     their sleep. Long story short, (blue and/or bright) light   
     in the morning is a win, and in the evening, it's a bust.
