Overall, Taekwondo seems to be helping Benjie to become very fit in mind and body, focus at school and become a well disciplined big brother at home. He also is developing good management and people skills. I don't see how that's a bad thing especially when we consider how so many children in this country face ignorance, mental illness, obesity, and tons of other societal problems.
I agree. Kudos to your son as well, taking the initiative like he has.
