Chess and Headache.

I get headaches by listening to people complain about headaches.

(Edit: If my comment came across as rude, I can understand why. Please note that I was not intentionally trying to make the op feel like an idiot. If I was, I would try a lot harder.)

Are you sure you haven't any visual issue? I'd ask a doctor about that.

wqrhmd,

Don't let people make fun of you. When I took the GRE to get into graduate school it was hour after hour of intense problem-solving questions, like which boats in which order carrying which people across a river would be optimal, or which cars of which colors could be on which floors of a parking building under certain constraints. I had a bad headache by the time the test was over. Like any other part of the body, the brain uses energy, blood, and other resources to function, and if you stress it too long, you'll start to feel pain. I claim that's normal for any heavy intellectual activity for a long enough time, especially under stressful conditions like time constraints.

It was only a jerk who made fun of him.

Thanks for replying everyone. I guess i was stressed that's why that happened. @sqod Thank you a bit more :D, you are reply was helpful #StressRelieving
