Confessions of a serial snoozer are no yawn

I used to think sleep and I were best friends. We can't wait to meet up again and are always on the same wavelength. Even notorious keeper-uppers like jet lag and caffeine can't break our bond. In fact, I rather enjoy getting home after a long flight and having a nice, strong coffee before I turn in for the evening. Or morning. Or afternoon. The time of day means nothing when you're a serial napper.

But now I'm not so sure. I'm starting to think our relationship is actually a bit unhealthy.

I blame a survey that was carried out to mark last month's edition of the annual World Sleep Day. It found that 76 percent of Chinese aged 10 to 45 have sleep disorders, while only 11 percent of the nearly 60,000 people surveyed said they could regularly snooze uninterrupted for the entire night.
