1) Thinking, Fast and Slow: Two systems

Hello there!
I am now reading really amazing book which is called Thinking, fast and slow. It is https://i0.wp.com/ecx.images-amazon.com/images/I/71wvKXWfcML._SL1500_.jpgwritten by Daniel Kahneman who has got nobel prize for economy. It is absolutely amazing so when I want to read I am not sure if I should rather read Game of Thrones or this one. Well, It is so good that I will even write what I learned from it.

It is about thinking: People think in two different ways using two different systems: 1 and 2.
When you are using system 1 you are acting without you even noticing.
But using system 2 you are probably solving some more serious problem and your mind is awake.
System 1 is in use always, he is really good in telling you if something is going on, what are people around you doing and it can alert system 2.

You see that this person is angry on someone and it is probably saying something bad (I am nearly citating the book). This is what your brain does almost always and this way is prejudice also created so system 2 (you) should check decisions of system 1. Problem is that system 2 is usually lazy.
When it comes to using of system 2 you will use it when I give you this question: How much is 17×28? You probably needed to stop on a while because system 1 realised that he does not know, only thing he can say is that it is larger than 200 and smaller than 800. Then system 2 starts to count it.
Many physical things will happen to you like sweeting or higher pulse. If you have good working memory it wont take you a long time to do it from head, it  is 476.
Well this was just a start so maybe next time I will continue.
