Lately I have been prone to headaches. They are mostly related to work. Not so much the work itself, but more the way it has to be done. Sitting in a chair. There are not many ways to do programming while walking around or doing sit-ups. Forget about push-ups. None of that can be done if you need to work on a keyboard.
Last week was a week of horror for me. Four days and nights of a low and medium grade headache. None of the advertised pills/gels/powders had any effect. So it was time to do something else.
