How is chess good for the human brain?

Chess is not good for your brain you mean?

It' actually good for your brain. it teaches you to think of every possible circumstances. You tend to make less mistakes, makes you a genius.

Chess encourages thinking and effort. That is what makes it good for you. 

Your all pretty much correct 

Fun fact: As we age our brain tends to lose its power. That is why its important that we all keep learning. 

Chess is a great way to learn!!!!

Never mind xD

Lets all go back on topic, now this is a bit of a personal question. Does anyone here want to become a doctor one day?

What are your dreams?

Agreed

I would recommend this game for people who want to become a genius. 

It is one heck of a tough game and requires a lot of work in order to get decent. 

For those people suffering from memory lost or a certain brain condition, try to work on studying. Even tho it may not seem to do much, trust me it will help a lot. 

Every moment in life counts, so make the most of all. 

Doctor and GM at the same time are both very possible so achieve. It just takes hard work like all other jobs. Besides what kind of doctor are you trying to become?

I am a doctor. I had to drop playing serious chess and OTB tourments in medical school as it was a considerable waste of time.  I am now playing chess online off and on. 

it isn’t.

"Chess holds its master in its own bonds, shackling the mind and brain so that the inner freedom of the very strongest must suffer." - Einstein

in order to win a chess game you don't have to play perfectly, only better than your opponent.

to win a chess game you just need to play against a bigger idiot.
