There's an article in the Telegraph about premier league football clubs hiring "sleep coaches" that has all kinds of sleep nuggets. In the first place, it's quite interesting that top clubs have such coaches and a recognition of how important sleep is to well-being and recovery. But even more of an eye-brow might be raised to learn that some players use musical pillows to improve their sleep. There is advice on mattresses (they should be completely white) and the insight that players sometimes sleep between training sessions. Also, there are players who have 12 hours sleep per day.
What a spectacularly good life that must be. Absurdly high wages, a playboy lifestyle and as much as sleep as you can manage.
