A surprise productivity tip - posture edition

Try this, I went through an abnormally focused period today and it seemed to be caused by a slightly different posture.

1. Sit in chair normally with good posture, nothing special.
2. Arch back slightly
3. Lean forward about 3 inches more than normal
4. Open your eyes about 5 millimeters more than normal

See if that works. I happened into it today and it seems to bring a much higher degree of focus than one might think.
