Sifu Herrera: I would love to attend one of your classes and, perhaps, to begin studying under your tutelage. I'm an old guy, but achieved the rank of Shodan in Tae Kwon Do in 1978. I dabbled with it since then. I, however, got sick and have been bed-ridden for quite some time. I'm better now, but very out of shape. Would you consider a student with the above description, and 66 years of age?
