I am happily, pleasantly, and mostly stress free right on pace with the PhD, thanks for the concern! I realize that a quick mental break can be vital when doing research or writing, and a quick visit to this forum is often enough to re-fire the synapses and take off again. Sometimes there are those paragraphs or sentences that can only be ingested in small bites, and you need to let your brain "breathe" in between. That, and it helps to be able to type at about 100 wpm.
