好久没去图书馆了。。。几年了吧?
今天起身没事做,就到旅店附近的公共图书馆去看书。
好久没好好看一本可以增广知识的书了。
我想我现在的普通知识还差过小六生吧。真惭愧!
印象深刻的是“HowCaffeinWorks?” 和 “HowSleepWorks”。
你可知道?The half life of caffein is 6hours. So if u take one big cup of coffee at 3pm, by 9pm u still have half of the caffein effect in ur system, and end up u losing ur chance of having a good quality sleep. (means even though u can sleep even right after drinking big cup of tea/coffee/alcohol, but ur quality of sleep is actually not good.)
A good night sleep for a normal person should contain about 5 cycles of [sleep (no dream) + deep sleep (with dream)] in a night. If u are sudden wakened up by someone during ur dream, u might be very frustrated and start jumping up and down. So, dream is very important for all of us! So, how long u dun have a dream during ur sleep liao ?
一个成人需要7-9小时的睡眠(因人而异)。睡觉有很多好处!
是时候上床睡觉了。。。
你多久没发梦了呢?
勇敢去发梦吧!
现在10PM了,好想泡杯Cappuccino来喝。 可以吗? 嘻嘻。。。
