I thought training doesn't increase intelligence. Does it?

It may not directly increase intelligence but it will solidify what you know. Explaining something to others requires a deeper level of understanding in my experience. It will also show you what areas you don't know and give you opportunity to learn those things as well.

The brain is plastic, why wouldnt intelligence also be so? https://en.wikipedia.org/wiki/Neuroplasticity

>Neuroplasticity involves the higher cognitive functions as well as memory and motor and sensory functions. No part of the brain is an exception. IQs of retarded individuals have been raised. Even thought and imagination, as brain scan technologies have clearly demonstrated, can change the structure of our brains.

Even if that is the case, what you are basically saying is: "Why try getting better at anything?". I can't see that as a functional path through life.

Well, I meant different things. He probably should apply a right tool to the problem? Like take a vacation, skiing or something, read non-technical book, sleep more etc?
