A lack of sleep is a bigger problem of course than just being tired. People with insomnia are four times as likely to suffer from depression and are at greater risk of heart disease, obesity and diabetes. It causes more time lost at work and lowers enjoyment overall.
Despite five decades of modern neuroscience, we have only a very limited knowledge of the role of sleep and barely know anything about the role of dreams. Common experience tells us to agree with Shakespeare's simple conclusion that sleep "knits up the raveled sleeve of care."

The judge presiding over the 9/11 case at the Guantanamo military hearings had one of the five co-defendants forcibly removed from the courtroom after he objected that he was being deprived of his right to meaningfully participate in his case.
