We have a harder time falling asleep Tuesday night.

周二晚上更難以入眠。

We don't spend much time tossing and turning in bed -- just a couple minutes a day on average. But that time peaks on Tuesdays, not coincidentally the same day we work the hardest. Sleep comes easiest on Friday nights, when we rest easy knowing the weekend is ahead. But sleeplessness creeps back up as we head into Monday.
