I dont need to disagree to you. Because you dont experience head aches or sore eyes as a programmer does not mean others dont. Most hardcore programmers i know always complain about the same thing. I have been coding for almost 20 years and well i also experience headaches although its much better now than when i started. You might want to read other programmers opinion around the world

The matter is not straight forward like that sha. Programming itself can cause headache make we no lie. . . . . .[s]I had to buy an external 20 Terrabytes R.A.M to boost my brain plus a 50 Terrabytes external backup device[/s]

I get this headaches (like the one that brought me here) only when working with languages that use interpreters, they don't point error until you run them, after edit, run, edit run and no show, you get frustrated or when I have a logic error am trying to figure, worse when editing another person's code.

I also realized that the projects I handled in 01,02 etc aren't as complex as the ones now.

Now I just wait for opportunity to sleep at night without waking in btw (as I don't sleep during the day) to fix the headache
