And this idea has been around for over two thousand years. The first good samaritan comes from a bible parable in luke chapter ten, verse twenty five. Jesus is giving a talk to a group of jews when a lawyer in the crowd stands up and interrupt jesus with a pRobing question, what must I do to inherit eternal life? Which is another way of asking, what is the purpose of jesus? Understood this was a test, and chose to answer the question with another question, as he often did, what is written in the law? He replied, how do you read IT? The lawyer answered, love the lawyer. Er god with all your heart and with all your soul and with all your strain and with all your mind and love your neighbor as yourself you have answered correctly jesus replied, do this and you will live but the lawyer wanted to justify himself and who is my neighbor? In reply, jesus tells the story of the good samaritan a man was going down from jerusalem jerrica when he was attacked by robbers ers. They strip him of his clothes, beat him and went away, leaving him half dead. A priest happened to be going down the same road. And when he saw the man, he passed by on the other side, so too, or leave, right, when he came to the place, and sim passed by on the other side. But as some merit as he traveled, came where the man was. And when he saw him, he took pity on him. This astonished the listeners for juice. And americans despise one another. The some american went to him and managed his wounds, pouring on oil and wine. Then he put the man on his own donkey, brought him to an end and took care of him. The next day, he took out two dinner and gave them to the in keeper look after him, he said, and when I return, I will reimburse you for any extra expense you may have. Then jesus asks, which of these three do you think was a neighbor to the man who fell into the hands of robbers? The lawyer reluctantly admitted the one who had mercy on him. Jesus told him, go and do likewise. This story is simple, yet has endured. The tests of time for IT reveals how to have a meaningful life, treat others the way you want to be treated, love your neighbor as yourself, the idea of being a good samaritan has transcended religious affiliation and has become a foundation of what that means to be a decent human being. Sadly, many people in modern society spend so much time staring at screens that they have become detached from reality when conflict arises. Many people's first reaction is to, without their phones and record as a tragedy and fault. And these tragedies are uploaded to the web for everyone on earth to see. The misfortunes of seven point eight billion people are broadcast onto our screens for us to mindless lesly consume, to the point where we become numb and disassociate these events from reality. As a result, when real situations happen right in front of us, the condition response is to record the event rather than try to offer help. With all the chaos in the news and on social media, we can often feel powerless to affect any change on a macro o level. How can your kindness and empathy have any impact on tragic happening on the other side of the world? And the truth is, IT can't. There is nothing you can do to affect the events you see on your screen. The reality is we can't change the world, but we can change ourselves. We have the power to change who we are, to shape ourselves into a big king of good, to do the right thing, be mindful, be kind, act on compassion and take the high road. And if we all followed in the steps of the good, some american, this world would change overnight. You may not be able to change the world, but always remember, you have the power to change yourself. And that will change the world be the change you want to see in the world. If you act on compassion when the moment presents itself, you will have a meaningful life. Mark twins at at best, you're never wrong to do the right thing. So the next time you see someone in need, don't ask the question, is this my neighbor? The far more important question is, am I being a neighbor? Don't be the bystander that stays in the dark. Due is the good samaria, and you will move closer to a life of purpose. 叮咚，下课了，我感觉才过了五分钟。你刚才在发呆模式里。大脑帮你按了快进键，快进键时间还能快进。大脑有一个默认模式网络，在你发呆放空什么都不想的时候。自动开启。这个模式是大脑的待机状态。他不处理外界信息，而是进行内部整理、记忆、归档。我们感知时间靠的是大脑记录事件的数量。发呆时时间太少，时间就缩水了。所以不是时间变快了，是我记不住这段时间发生了什么。没错，你回忆刚才发呆的20分钟，能想起什么？几乎空白，大脑就觉得这段时间不存在。反过来，当你专注做一件有趣的事时，每一秒都有新信息进来。记忆点秘籍，时间就变长了。难怪假期出去玩感觉过得很慢，上课发呆感觉一眨眼就放学了。而且等待的时候时间会显得特别慢，因为你的大脑在不停的检查。时间过去了多久，越关注时间，时间过得越慢。就像水壶烧水，盯着它它永远不开。所以我盯着时钟等下课一分钟，像一年发呆不看钟，一节课上一分钟。想让时间慢下来就去创造新体验，走一条没走过的路，学一个新技能。所以不是时间不公平，是我的记忆在作弊。发呆也不全是坏事，它让大脑休息释放创意，很多灵感都是在发呆时冒出来。的那我可以理直气壮的发呆。一会儿了，平衡就好，该专注是专注，该休息时发呆，学会控制自己对时间的感知。记住了，发呆不是时间变快，是大脑在省电。总结一下时间快慢是主观感受，丰富体验时间就慢下来。谢谢李医生，我要去创造更多回忆了。好，科学感知精彩生活。 猫小帅快去睡觉。哎呀妈妈我不困，让我再看会儿。人为什么要睡觉呢？不睡觉的话就可以多看好多动画片了。一直不睡觉的话，可看不了很多动画片。你不睡觉我的时间就变多了。因为白天我们做了很多事情，大脑一直在工作，消耗了很多能量，产生了许多垃圾。如果你不睡觉，就不能把垃圾排出来，让大脑恢复活力，大脑也就不能正常运作了。在大脑里有河流里面充满了干净透明的液体，叫做脑脊液。大脑产生的垃圾会排到脑脊液里，再跟着脑脊液一起流到血液里，利用身体的循环系统把垃圾排出。他们不能换个时间排垃圾吗？睡觉时身体和大脑的强制维护与重启，核心是为了修复记忆，排毒、稳情绪、强免疫，缺一不可。一、身体修复，夜间大修，恢复能量，心跳、呼吸、肌肉放松，代谢放缓，为白天储备精力。组织修复，深度睡眠时生长激素大量分泌，修复肌肉、骨骼、皮肤与受损。细胞免疫，升级免疫细胞活性，增强抗体生成更多抗病力。提升内分泌平衡，调节食欲、血糖、压力激素，减少肥胖、糖尿病风险。2、大脑优化记忆加排毒，记忆巩固，把白天的短期记忆存为长期记忆，学习效率翻倍。大脑排毒，睡眠时脑脊液流动加快，冲走贝塔淀粉样蛋白等代谢垃圾，降低痴呆风险。提升认知，清醒后注意力、判断力、创造力更强。3、情绪与心理稳定器睡眠不足会让皮质醇升高，导致焦虑、易怒、情绪失控，充足睡眠帮你处理压力，平复情绪，保持心理稳定。 Hi, I have time to spare.
