Claims of widespread sleep deprivation in western society are nothing new - in 1894, the British Medical Journal ran an editorial warning that the "hurry and excitement" of modern life was leading to an epidemic of insomnia.

Even then it probably wasn't true. The fact is that most adults get enough sleep, and our collective sleep debt, if it exists at all, has not worsened in recent times.

Despite my best efforts, even post-sleep apnea I tend to fall into weird patterns. Lately I have found it harder to sleep in on weekends than weekdays; I don't know what that means.
