We need to bring back Agoge for our kids. Starting age 7. On a serious note, what's the average age for people enlisting now? I'm sure it's above 20. That's a problem in and off itself. Very hard to shape someone who has grown up soft as fuck for 20+ years into a killer. Lowering the age to 14, and providing the military as an "alternative" high school might be a good choice for a lot of people.
