After cutting this illustration the other day I realized that I have a really bad posture. I´m so concentrated on cutting the lines right that I simply forget anything around me, or about me, actually, and that includes how my back is positioned. At the end of the two hour session I realized there was something weird about my muscles and the next day I could hardly move.
I´ve been stretching my back periodically during the day, as well as wearing an extra layer of insulation for warmth; Paulo massaged my back with this weird smelling medicated cream and I can slowly move more and more without grinning. But simple things like sneezing remind me that I´m not fully recovered.
I think that after this warning sign I definitely have to watch my posture (I say as I straight my back).
