Ok so being smart is the ability to manipulate figures in one's head. That would make me smart. Therefore something must be terribly wrong with this definition.

I can hear a tune in my head, listen to the "same" tune played differently and tell you exactly which note is "wrong", high or low. To my brother playing a 12 string guitar... A conversation: me my bro

no thats wrong, it does not as good if you would just change...
Where is it wrong? Play it again. Stop, thats a little to high.

Can I actually play the instrument or read the music like my brother? Hell no. Have I tried? yes, I cant do it. I am bad. Can I hum the tune and hit the right note so he does not have to play a song again allowing him can change it easily? No. I cannot reproduce the sound. But I can hear in my own head, I am humming the wrong note. He has got to get it right or it wont work.

I swear if you do this just a bit higher it will sound perfect. Play what a bit higher? Play this part again (humming attempted). Hell I am having a hard time even tell what your are trying to hum. Brother plays it again with my suggestion. Thats it you got it That does sound a lot better. Stay here what??? so this can take forever?

I still humbly ask... What is smart? One catches on to information quickly and can manipulate it quickly... I think this is what our society deems smart. So most of the people on this board are probably very smart.

BTW, I have noticed the thing same that DTS has with spatial relations in males and females. I can give multiple examples.
