Here in New Zealand and many years ago now, Martial arts was taught at my school as part of development and health, plus we had Mau Rakau training in maori warfare/ customs and performance, I use to go away on training camps with my school, these camps ranged in the age of 10 to 17 years olds, actually last week I was at the local school teaching kids in age from 6 to 10 on the use of the Taiaha, https://www.youtube.com/watch?v=MVQNHFCG...
