My kids (ages 9 and 10) watch Jeff and Max's videos together too. I agree some of the content is a bit like (oh shit, kids go in the other room quick!) kind of stuff, but at the same time, I try not to shelter my kids too much. Let them hear the occasional curse words in the rap songs and see death occasionally. We discuss literally everything and use adult language with them, always. Lessen the blow a bit for them imo, since I know some really scary times lie ahead of us. De-sensitize them just enough so that when the SHTF soon, they will react appropriately, even help my wife and I take the life of anyone who dares to break into our home (they are both green belts already in aikido, judo, kempo, karate and multiple weapons like the sai, nunchucks, bow, philipino sticks, sword and of course their sharpened machetes). Let's show our kids how to respect life, and take it when left with no choice. #nofear
