Question:
Why do you get a headache when you think really hard?
I just had a really, really hard time booking tickets from Ft. Lauderdale to NYC for a weekend shopping getaway, but OMG after like 5 hours of heckling with the airlines, checking fares and all that stuff, my head HURTS! Why? Chemical?
Answers:
5 hours is a pretty long time, it usually happens in less than 30 minutes.
When you think about something, there would be two kinds of logical activity in your brain, one you will learn, other you apply.
when you apply a logic, it usually doesnt take much effort and that is the reason brain takes more time to get pain.
when you learn something by thinking or reading, the process actually builds neural network(logic) in your brain which requires cell breakdown - a lot of heat flow which is a pain to itself.
