Japanese prevention exercices: Katsugen

When I was 17 to 21 I had very often a strong pain on my brow, I am not sure if it was migrania but I can say that I experienced fear when I noticed the first "signals" because that mean 3 or 4 hours of constant pain.
Very near my home in Barcelona, Spain, a Japanese man created a fundation called Seitai with the objective to teach the practice of Katsugen undo (http://www.seitai-cvp.com/katsugen-undo-2/) Since 1997 I started progressively practicing it, first "erased" my headaches, and then my muscle "blockings" and now I practice it every day just because it helps me to feel better. It is an important part of my life. I cannot imagine my life whitout making use of it.
This are very simple exercices which you can practice at home withou any cost.
Katsugen is not therapy, is prevention.
