Behind the Boom of Brain Training

What is called 'brain training' or 'logical thinking' is booming among the people in Japan.

I don't know whether I should say 'brain training' and 'logical thinking' in the same context (these words may be quite different to some people), but anyway I can see many books titled 'brain training' and 'logical thinking' in the amazon.com.

It shows that many people want to become more brainy/smarter than ever, doesn't it? I try questioning myself about it and it seems to me that many people, especially business people as well, think that they should be smarter on their own in their everyday life.

I don't know if it is good for them to become brainy. Let me assume some situation of chat: while we are chatting, I always try asking, "what is it?", "what do you mean by this?", "it doesn't make sense", "that part of your tale sounds illogical", and so on. It is as if we were always in a discussion/meeting in class at school. I would get tired if I were always asking and questioning while chatting.

The issue I would raise is," do we really have to be smarter/thinking logically everywhere and every time in our life?" To be honest, I am not sure if we should do.

I don't always respect people trying to be rational or logical: I would like to ask such a king of people, "what part inside you do you defend?" It seems to me that they are likely to care themselves only, or that they just try to look nice and smart. It is just as if I dressed up.

This effort for trying to be smart is a kind of the waste of the time and money. Anyway it doesn't always help.
