回复：“如果能熬夜还啥事都没有”哈，有谁不羡慕呢！可是有吗？

how about those people who work night shift, staying up all night working, or idling, but not sleeping.

they usually sleep about 6 hours or so, the next day during the day time.

compared that with people who sleep also 6 hours or so, will it be the same, health wise?
