Weird topic already, it struck me today while I was nodding off in the class this morning that time available to us is actually very limited. Think about it, we had already used up at least eight hours a day for sleep, that is a-third of a day doing nothing. To make it more drastic, we actually spend a-third of lifetime sleeping. Ironically, most of the students still nod off in the class. I don't want to be judgmental here because I myself do the same thing all the time. Maybe it's a good starter for serious thinking on our sleep.
