Hi all, Maybe someone can help.. If a 1st Degree Black Belt in Kenpo Karate with 3 years in grade gets the rank of Black Belt Instructor would this make him a 2nd Dan or would he still be a 1st dan?? Or can someone tell me what is the equivalent to this rank in Kenpo Karate?

I read a number of times that 7 hours is the right amount of sleep. People that sleep more then 7 hours are found to be just as tired as people that sleep less. It is also said that people that sleep 7 hour are healthier and live longer.
