Goddamn. I went to Karate (Yellow-Black basic techniques) lesson 14.00. It was nice but I thought I stay for one extra lesson and asked if I can join the white-belts for another torment. It seems now that it was a mistake. My back is telling me that it is going to suicide, but I don't worry about it too much as I might black out first from the tension on the neck and shoulders. It is so nice to have hobbies.
