I think this needs saying. I see so many little fat beasts running around and in my mind that's borderline child abuse. Please teach your children about health and fitness because it's equally important to anything else that you're going to teach them in life.
Enroll them in sports, get them interested in physical hobbies such as backpacking, climbing and mountain biking. Put them through a year or two of MMA training so they know how to protect themselves. Bottom Line, stop feeding them garbage and letting them sit inside and play video games all day. We want this new generation of children to be strong both mentally and physically.
