no one really knows, he was a person, who either either knew a lot of what he was talking about. Or as adam gb said someone that read something out of a book. The person sent a long letter about how alex was a boxer in the school, who maybe thought he was hard or something. So this person called simon who went to the school decided to embaresse him on saddoboxing and probably got carried away. Even if it was alex or not i would listen to some of the advice he gives because lots of it is very good.
