As for kids, I work with kids for a living and let me tell you, Primal has made things MUCH easier with them. I tire them out, not the other way around. I'm able to tire out my 15 year old brother and his friends. The energy, the freedom of movement, is such a huge benefit. If I ever have the pleasure of being a father, I'm gonna be one of those dads that are able to keep up with their kids, do stuff with their kids ... not sit around sadly and watch them do things. Keep it up man, it's totally worth it when it comes to kids.
