Most people need to prioritize sleep. There's just too much in our society that distracts our attention elsewhere.

When you're sleep-deprived, you're prone to performance problems. It affects your decision-making, how crisp you are in dealing with things, what your mood is. Sleep needs to be a priority.

A lot of people are paying attention now because people are wondering, as we overmedicate our society, is there something else that it could possibly be, that we're missing?

The incidence of sleep disorder has been rising, but people are not paying enough attention to it.

People tend to be irritable. They have impaired daytime function. There is data to suggest that people that have sleep disorders are more at risk for depression.

Believe it or not, despite all that we know about sleep, we don't know why people sleep or what its purpose is.
