Hi,Computer Freak. I read your letter and learned that you have health problems but to long sitting at the computer.I will try to help you. Headache and eye pain arises from a large number of magnetic radiation from the computer and monitor.Even because of the incorrect position of the spine. Dear Freak,when you a long time at the computer,periodically do a light workout the eyes and body,separate the time in little breaks and go to sleep at night not less than eight hours,eat vitamin D. I advised the most basic thing you need to do,I hope this helps and you wont suffer from the terrible pain in body.если что то не правильно, или не понимаешь объясню.
