Kung Fu is said to have been created by small men who are quick. But as the argument goes, in the North people were big. But in many classes today, teachers will use the bigger students to demonstrate on, or will teach smaller students ways of dealing with bigger attackers, and at times may seem to pay more attention to the smaller students. What about big guys learning on smaller attackers? I for one am kinda big and slow and have a problem with dealing with the smaller quicker guy. Do you feel nowadays the big guy may be at a disadvantage when it come to learning? If not, how does your school deal with it?
