Took a while to get it but I can see your final point. Still must note that it makes applying critical thought harder and can lead to opposite results. I guess it would work with people with whom it is established beforehand what the battery is supposed to mean.

The first point, thanks for the insight. Depending on the type of pain it can be the opposite for me, sometimes I find it easier to distract myself from it by talking to others. I am normally not inclined to talk IRL, but being badly ill and weak turns me into a more pleasant person apparently.
