世界睡眠日

我还真不知道世界睡眠日是三月二十一日。
据说国际公认的三项健康标准是，均衡的饮食，适当的运动和充足的睡眠。

Sleeping is no mean art: for its sake one must stay awake all day. 你知道这是谁说的吗？Friedrich Nietzsche(尼采)。
No day is so bad it can't be fixed with a nap. -- Carrie Snow
People who say they sleep like a baby usually don't have one. -- Leo J. Burke

If you can't sleep, then get up and do something instead of lying there worrying. It's the worry that gets you, not the lack of sleep. -- Dale Carnegie

据说一个人只喝水不进食可活七天，而不睡眠就只能活四天！
听说有一种familial fatal insomnia(家族性致命失眠)，它会遗传下去。父母一人有病，子女就有一半机会患上。通常五十多岁发病后便无救，一直过累致死。够恐怖的。

能舒服地美美地睡上一大觉，实乃一大快事。
